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.
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. Calculus, Contemporary Calculus, Hoffman. Polar. Lesson HOW TO - Solve Trigonometric equations. 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. 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. 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.

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)!

Karl's Calculus Tutor - Sending Math Notation over Email. If web page options leave something to be desired with regard to rendering math expressions, email can be a nightmare.
But on various math discussion usenet groups, some standard notations seem to have evolved. Basic Guidelines: First, before you compose any math expressions for sending over the email, you should set the font of your email composition window to an equal-space font like Courier. This will assure that columns will line up the same way for both sender and receiver. Also it is very important to remember to press the enter key before you reach the 80th column of each line.

0.2 About The Chaos Hypertextbook™ Prev | index | next 0.2 About The Chaos Hypertextbook™ Who? You and I. I wrote this book for anyone with an interest in chaos, fractals, non-linear dynamics, or mathematics in general. It's a moderately heavy piece of work, requiring a bit of mathematical knowledge, but it is definitely not aimed at mathematicians. A Fractals Lesson - Introduction.
They're everywhere, those bright, weird, beautiful shapes called fractals. But what are they, really? Fractals are geometric figures, just like rectangles, circles and squares, but fractals have special properties that those figures do not have. There's lots of information on the Web about fractals, but most of it is either just pretty pictures or very high-level mathematics.
So this fractals site is for kids, to help them understand what the weird pictures are all about - that it's math - and that it's fun! Fractal. Figure 1a. The Mandelbrot set illustrates self-similarity. As the image is enlarged, the same pattern re-appears so that it is virtually impossible to determine the scale being examined. Figure 1b.
