Consider the integral 2*(2* – 2)*dz. Tojfind jthe value of thj integral, make the substitution u 26 – 2. %3D a) Write (2° – 2)° in terms of u: b) This makes da = |du c) Re-write the integral in terms of u and du, and find the antiderivative. The antiderivative in terms of u is: d) Now back-substitute and write your answer to part (c) in terms of r:
