两个数值实验的matlab编程实现。题目分别1是利用循环语句，计算数列根号5 ，根号下根号5 ，根号下根号下根号5…的极限，要求误差小于 10负8次方。 2利用级数pi=1-1/3+1/5-1/7+...可计算出无理数pi的近似值(Two numerical experiments matlab programming. Title 1 is the use of loop were calculated series roots and 5, roots and root number under 5, roots and root, root number under number 5 ... the limits of error of less than 10 required a negative 8th power. 2 using series pi = 1-1/3+1/5-1/7+ ... calculate the approximate irrational number pi)

Skydiving Simulation. Simulation can help predict position and velocity of a skydiver who jumps an airplane and opens a parachute. In this tutorial, we predict the position and velocity of a skydiver in two dimensions (horizontal and vertical) the time of the initial jump through the first 90 seconds.
