How do you integrate the following function:  
    square root of (1 - x squared) from 0-1?

Use the substitution x = sin(u).

Another way to do the integral you ask for is to realize

1. The integral asks for the area of a region
   between a curve and the x-axis

2. The particular region in this problem is one quarter of 
   a circle of radius 1.

(so the answer is pi/4)
