how i can evaluate it1. The problem statement, all variables and given/known data
what is the integral of sin(x^2) dx?
2. Relevant equations
3. The attempt at a solution
No, "sin x^2" MEANS sin(x^2) and cannot be integrated in that way. If your function is really (sin(x))^2= sin^2(x), you should have told us that immediately.sin x^2 = 1 - cos 2x
and we can use 1 and cos 2x seperatly and solve this problem.
Why is this true?dx=cos(x^2)dm
