EXAMPLE:

integral is of:

4*(sin(theta)^4)*cos(theta) dtheta

the limits are pi/6 to 5*pi/6

i had u= sin(theta) ... both the u lower and upper limits equal 1/2...

the original integral was a double integral in polar coordinates... limits of r was o-2sin(theta) and i already stated the theta's limits. the function is (r^3)*cos(theta)

it doesn't make sense to me to let u=cos(theta) in this case of

"integral is of:

4*(sin(theta)^4)*cos(theta) dtheta"
