The answer: 0.632

How do I get to that answer? Do I find the antiderivatie and solve for F(x) when x=8?

**Katie**, Monday, January 11, 2010 at 8:36pmAlright, I found -1/4cos(x)^4 but I didn't get the right answer.

Did I dint the wrong anti-derivative? Do I have to do reverse chain rule and get... (-1/4cos(x))sin(x)^4?

**Anastasios**, Wednesday, February 17, 2010 at 2:16amYour antiderivative is not correct.

You need a u substitution. Or if you have not learned that try NINT in the calculator.

For the u substitution, let u = cos x and du=-sinx . (this is after you changed the integral to sin^3x = sin^2x *sinx =(1-cos^2x)(-sinx). Don't forget the - sign in front of the integral too. Then do the u sub
