4. (10 points) Use trig substitution to rewrite / V1 -12 dx so that it can be integrated with just a simple u-substitution. Simplify as far as possible so that I could integrate your answer in one step. DO NOT integrate 5. (10 points) Jessica used the trig substitution a = 2 sine to integrate / MAT dr. She arrives at the answer 2 In | csco - cote| + 2 cos 8 + C. Rewrite the answer as a function of c
