This problem involves a change in variable of the limit of integration.
Consider the area bounded by , y=0, x=0, and x=.5. A definite integral of this area, using x as the variable of integration, is
. The next part of the question says: make the substitution of the form to transform the integral so that is the variable of integration.
I'm not sure how to start this one. I thought of simply solving for , but I'm don't know how to transform the integrand.
*edit* forgot my dx. x.x
