Use the plane y = x , range of x is same as y
Write a triple integral to represent the volume of the solid
The wedge in the first octant and from the cylinder y^2 + z^2 <= 1 by the planes
y=x, x=0, z=0
First..
i find the range for z..; 0 <=z<= sqrt(1- y^2)
then...
i find the range for y..; let z =0
0<=y<=1
next, if i let z = y = 0
how am i going to find the range for x?
