1. The problem statement, all variables and given/known data Use the product rule to differentiate the function: h(t) = √t(1-t2) 2. Relevant equations d/dx[f(x)g(x)] = f(x)g'(x) + g(x)f'(x) 3. The attempt at a solution (see attachment image) I checked the back of the textbook and my solution was wrong. The textbook says the answer is (1 - 5t2)/(2√t). What did I do wrong? How do you get this answer?
