1. Show geometrically why int sqrt (2-x^2) dx = pi/4 + 1/2
2. Approximate int sqrt (2-x^2) dx for n = 5 using the left, right, trapezoid, and midpoint rules. Compute the error in each case using the answer to question 1 to compare the errors

Show geometrically why .
This is an equation of a circle with radius sqrt 2 as shown above.
The given integral is the area of the circle from x = 0 to x = 1 in the first quadrant . I have shaded this area in the first diagram.
Therefore the value of the integral = Area of the shaded region.
We will find this area using geometry. We need to find area ODAC.
Area ODAC =Area OBC - Area of OAB + Area of OAD(this is a ...
