Suppose we want to evaluate the definite integral, r2502 - 4r2 dr using the substitution, = Part 1. 16 2502-4r2 Re-write the definite integral in terms of the variable u and remember to use the limits of integration for the function u = f(r). Then, input the antiderivative of the integrand and the limits of integration you found. Note: Type your answers above in such a way that the lower limit of integration is less than the upper limit of integration. Part 2.
