Question

find the area of the region enclosed by the lines and curves
1. x=2y^2, x=0, y=3
2. 4x = y^2 - 4. 4x = y + 16
3. y = sinx, y =x, x = pi/4

Answer 1

This can be done by drawing the graphs of each function. Then mark the limits between whic the area is required.
Then integrate from lower limit to the upper limit.

Answer 2

Depriving you of the pleasure of finding the solutions to these would be sinful.
