Confused with solution
Fragment of a discussion from Science talk:Math Exam Resources/Courses/MATH103/April 2010/Question 4 (c)
Don't forget the extra factor 1/(-1) which comes by taking the derivative of the inner function (2-x). Same with the second integral which needs an extra factor of 1/2 since (1+2x)' = 2. Does this make it more clear?
