The Pi Trivia Game
part of Pi Land

Finally this is your chance to pay tribute to the magnificent transcendental number that we have all grown to love! Test your knowledge of history, mathematics, and even a little physics.

Here are 25 (given to you 5 at a time) fun pi-related questions, picked randomly from my exciting pi question database! Get ready for the thrill of your lifetime, the ultimate challenge, The Pi Trivia Game!

Pi Flower
1. There was a time (a while ago) when people were trying very hard to 'square the circle.' It was said at the time that it was even an illness and a name was given to it. What is it?
Squarerootofpitis
Impossibilus Fittis
Morbus Cyclometricus
WileECoyotisandRoadRunneritis
Repetitionatis Decimalus

2. What professor was dismissed from his position in 1934 for teaching in an "un-German" style after saying (correctly) that pi/2 is the value of x between 1 and 2 for which cos x vanishes?
J. Robert Oppenheimer
Kip Thorne
Scott Adams
Elias Bröms
Edmund Landau

3. What is the value of e^(i*pi)?
the square root of -1
approximately 10
pi squared
-1
1.414

4. Which of the following is NOT equal to pi?
4 * the integral from 0 to 1 of sqrt(1 - x^2)dx
4 * arctan 1
the ratio of any circle's circumference to its diameter
(3/4) * the number of radians in a 270 degree angle
2 * the number of radians in a right angle

5. What rapidly converging formula for calculation of pi was found by Machin in 1706?
pi/4 = 1 - 1/3 + 1/5 - 1/7 + ...
pi/4 = 4 * arctan (1/5) - arctan (1/239)
e^(i*pi) = -1
pi = 3 (close enough)
pi = 4 * arctan 1
