Problems 161-180 Last update: December 14, 2001 Rank in order these probabilities from least to greatest based on an ordinary 52-card deck. For purposes of this problem count all sets of five suited cards as a flush (including straight flushes and royal flushes). (A) Probability of a flush (B) Probability of a flush, given that the first card is an ace (C) Probability of a flush, given that the hand consists of at least one ace (answer) (solution) Five pumpkins are weighed two at a time in all ten sets of two. The weights are recorded as 16, 18,19, 20, 21, 22, 23, 24, 26, and 27 pounds. All individual weights are also integers. How much does each pumpkin weigh? (answer) A large tank has a steadily flowing intake and 10 outlet valves, the latter being all of the same size. With 10 outlets open, it takes two and one half hours to empty the tank; with 6 outlets open it takes five and one half hours to empty the tank. After the tank is empty and with all 10 outlets closed, how long will it take to fill the tank? (answer) (solution) A courier pigeon departs Las Vegas for Reno at the same time as another courier pigeon departs Reno for Las Vegas. Both pigeons fly at constant speeds, although different from each other. They cross paths 2x miles from Las Vegas. After each arrives at their destination they immediately turn around, going back and forth without breaks. They cross paths the second time x miles from Reno. Where will they cross paths the third time?

A Bracelet of Numbers by Don Allen, National Aboriginal Career Symposium, Ottawa, Canada The numbers that we deal with in this simple investigation are the ten digits, to 9. Choose one such number. Choose a second, which need not be different. Obtain a new number by adding the first two numbers, and recording only the ones digit of the sum. Thus, for 8, 9, we have 8, 9, 7, ..., the start of an unending sequence. Obtain a "next" number by similarly combining the final two. The sequence becomes 8, 9, 7, 6, 3, 9, 2, 1...Continue. Predict what may happen, and investigate to see if you are right. Try, at leisure, a triple of starting digits instead of a pair. How, otherwise, might the procedure be modified to produce different, but interesting, results. Hailstone Numbers by Don Allen, National Aboriginal Career Symposium, Ottawa, Canada

A Note on the Centrifugal and Coriolis Accelerations as Pseudo Accelerations - PDF File On Expansion of the Universe - PDF File Note to the student: The following section is a reduction of college notes I made in introductory thermodynamics. It does not read as easily as the preceding sections. I include it here because, for me, it represented a significant unification of the ideas presented in the text and during lecture. The first year college student will certainly find it useful. The equation of state for an ideal gas is pV = RT where p is gas pressure, V is volume, is the number of moles, R is the universal gas constant (= 8.3144 j/( o K mole)), and T is the absolute temperature. The first law of thermodynamics, the conservation of energy, may be written in differential form as dq = du + p dV where dq is a thermal energy input to the gas, du is a change in the internal energy of the gas, and p dV is the work done by the gas in expanding through the change in volume dV.

89. Math::BigInt - Arbitrary Size Integer Math Package Autocreating constants. After use MathBigInt 'constant' all the integerdecimal constants in the given scope are converted to MathBigInt . http://www.perl.com/doc/manual/html/lib/Math/BigInt.html

NAME SYNOPSIS DESCRIPTION EXAMPLES ... AUTHOR NAME Math::BigInt - Arbitrary size integer math package SYNOPSIS DESCRIPTION All basic math operations are overloaded if you declare your big integers as $i = new Math::BigInt '123 456 789 123 456 789'; Canonical notation Big integer value are strings of the form with leading zeros suppressed. Input Input values to these routines may be strings of the form Output Output values always always in canonical form Actual math is done in an internal format consisting of an array whose first element is the sign (/^[+-]$/) and whose remaining elements are base 100000 digits with the least significant digit first. The string 'NaN' is used to represent the result when input arguments are not numbers, as well as the result of dividing by zero. EXAMPLES '+0' canonical zero value ' -123 123 123' canonical value '-123123123' '1 23 456 7890' canonical value '+1234567890' Autocreating constants After use Math::BigInt ':constant' all the integer decimal constants in the given scope are converted to Math::BigInt . This conversion happens at compile time. In particular perl -MMath::BigInt=:constant -e 'print 2**100' print the integer value of . Note that without convertion of constants the expression 2**100 will be calculatted as floating point number. BUGS The current version of this module is a preliminary version of the real thing that is currently (as of perl5.002) under development.

Math Skills Review Algebraic Manipulation The key to solving simple algebraic equations containing a single unknown (e.g. x + 6 = 10) is to realize that the equation is an equality. As long as you do the same mathematical operation (e.g. add a constant, subtract a constant, multiply by a constant, and divide by a constant) to both sides of the equation, the equality is still an equality. This includes squaring both sides of the equation or taking the square root of both sides of the equation. Fundamental Laws: Distributive Law: 3(x + 2) = 3x + (3)(2) = 3x + 6 Associative Law: 4x - 7x = x(4 - 7) = -3x Example 1 To solve for x, it is necessary to subtract 6 from both sides of the equation Example 2 To solve for x, you need to add 6 to both sides of the equation and then divide both sides by 2. Example 3 To isolate x, you need to (1) multiply through by 6, (2) subtract 2 from both sides, and (3) divide both sides by 5. Example 4 To solve for x this time, you need to (1) multiply both sides of the equation by 4 and 3 to cancel out the denominator in line 2, (2) use the distributive law

CTK Exchange Front Page Movie shortcuts Personal info ... Recommend this site Star Construction of Shapes of Constant Width The Reuleaux triangle is the simplest (after the circle) example of shapes of constant width. The applet below shows how to construct other, less regular, shapes of constant with by starting with star polygons. Start with an equilateral, but not necessary equiangular star. Proceed as in the case of the Reuleaux triangle. Specifically, use vertices of the star as centers to draw circular arcs of the radius equal to the side of the star. The arcs should connect pairs of adjacent vertices. If we think of the arcs as bridging between the sides (or their extensions), we could draw arcs of a radius augmented by some positive quantity a. This creates gaps at the vertices of the star that could be filled with arcs of radius a. Vertices of the star are draggable. The foregoing constructions will produce shapes of constant with as long as all sides cross each other and the number of vertices is odd Alexander Bogomolny The number of vertices in the star construction of shape of constant width is always odd. Indeed, mark a vertex and the opposite arc. Count the number of vertices and arcs between the marked vertex and the marked arc. To the left of the marked vertex there will be, say, LV vertices and LA arcs. To the right of it there will be RV vertices and RA arcs. Since every arc follows a vertex and vice versa

Home page. Math Trek Catching Flies Food for Thought FDA Launches Acrylamide Investigations Science Safari A Prized Worm TimeLine 70 Years Ago in Science News Week of Oct. 12, 2002; Vol. 162, No. 15 Catching Flies Ivars Peterson Archerfish and baseball outfielders appear to use different strategies to snag a projectile. Archerfish ( Toxotes jaculatrix ) are famous for their unusual way of hunting insect prey. Upon spying an insect on a twig or a piece of foliage hanging above the water surface, the fish shoots it down using a strong, accurately aimed jet of water. Once dislodged by a shot, the insect tumbles down, following a roughly parabolic path. Archerfish typically swim around in shooting parties. Often, more than one fish spits at the same target. And, when a bedraggled insect hits the water surface, it's first come, first served. So, it's to a shooter's advantage to be able to predict a waterlogged insect's landing place and get to it as rapidly as possible. Experiments now suggest that an archerfish needs just a quick glance to judge where the dislodged prey will later hit the water and promptly moves in that direction well before the insect splashes down. "In contrast to other known examples of three-dimensional target interception in man and animals, archerfish can head straight to the predicted point of catch without the need for any further visual feedback," biologist Stefan Schuster and his collaborators at the Albert-Ludwigs-Universität-Freiburg in Germany report in the November Journal of Experimental Biology

(animated GIF version) GRAPHICS FOR COMPLEX ANALYSIS Douglas N. Arnold This is a collection of graphical demonstrations of concepts in complex analysis which I developed for a course I gave on that subject during the spring semester of 1997. (For graphical demonstrations of calculus concepts see my page on Graphics for the calculus classroom .) Please send any feedback concerning this page to me by email The most common method of visualizing a complex map is to show the image under the map of a set of curves, e.g., a set of line segments of constant real and/or imaginary part (a Cartesian grid), or a set of concentric circles and spokes (a polar grid). A weakness of this approach is that it can be difficult or impossible to infer which points of the original curves are mapped to which points of the final images. The graphics on this page use two techniques to overcome this problem. First, most are animated so that the original curves are continuously deformed into the image curves, and the eye can follow which points move where. Second, I use colors to distinguish different points and curves. Viewing instructions.
