The Pi-Search Page The Pi-Search Page Why can/can't I find my number in Pi? If we view Pi as a big, random string of numbers (which is close enough for our purposes), then we can figure out the odds of finding any string in the first 100 million digits of Pi: Happily, if you include the zeros, birthdays are 8 digits long -- so you have a 63% chance of finding your birthday in the first 100 million digits of pi. Now that we're to 200 million, the odds are up to 86%, so it'll be a while before everyone can find their birthday in Pi.
Exploring Multivariable Calculus Exploring Multivariable Calculus Welcome to Exploring Multivariable Calculus! This website is dedicated to exploring calculus visually using the computer. In particular, it's focused on helping you explore multivariable calculus and some three-dimensional topics within single variable calculus.

Introduction The solution of trigonometric equations is one topic that students have particular problems with. There are a few reasons for this: 1. there is usually a simplify part first that requires use of some TRIG identities. 2. there is the use of RADIANS rather than degrees, for which some students are not at ease with. 3. there is the repetitive aspect of TRIG functions that students find bewildering. All in all, a potentially daunting topic. Lesson HOW TO - Solve Trigonometric equations Lesson HOW TO - Solve Trigonometric equations
Function Visualizer Model Documents written by Wolfgang Christian and Francisco Esquembre The Function Visualizer Model displays the graph of a function f(x) with arbitrary parameters. The function can contain polynomial, trigonometric, and exponential expressions as well a parameters. Function Visualizer Model Documents
Summary of trigonometric identities
List of trigonometric identities These identities are useful whenever expressions involving trigonometric functions need to be simplified. An important application is the integration of non-trigonometric functions: a common technique involves first using the substitution rule with a trigonometric function, and then simplifying the resulting integral with a trigonometric identity.

Waves that act a bit like particles, sometimes, but which spread out and interfere with each other just like other waves. It’s about 200 years since physicists finally agreed that light behaves like a wave, after Poisson proved himself wrong with an ingenious experiment involving a surprising bright spot in the shadow of a disc. We could have come to that conclusion much sooner, if we had known what we were looking for, but nobody really thought about interference patterns very much in those days. Francesco Maria Grimaldi coined the term ‘diffraction’ in the 1660s, to describe his observation that light spreads out when it passes through a small hole.
Inverse Sine, Cosine & Tangent. How SOHCAHTOA can Calculate Angles. How to use these functions... Vs. Interior Angle Sum Compare This Method To the tried and true theorem that the sum of the interior angles of a triangle is 180°. What is the degree measure of Since the total measure of the interior angles of a triangle is 180 degrees we can verify the measure of Alternately, you could use the inverse of one of the SOHCAHTOA functions, in this case the inverse of sine (sin-1)!
