3. The attempt at a solution

since cos(x^2) is on bottom i flipped it and so it becomes negative. then I got

-[(1+cos(x^2))(-sin (x^2))(2x)]

substituting with sqrt(pi/2) I keep getting the answer as sqrt(2pi) since the negatives cancel however it says the answer is supposed to be -sqrt(2pi). What am I doing wrong?
