Evaluate integral( sin^3(x) cos^5(x) ) dx

2. Relevant equations

sin^2(x) + cos^2(x) = 1

integral x^n dx = x^(n+1)/(n+1) + c

d/dx cos(x) = -sin(x)

a^n*a^m=a^(n+m)

3. The attempt at a solution

I got -cos^6(x)/6+cos^8(x)/8+c

Apparently I did something wrong

Thank you for any assistance! I really don't see what I'm doing wrong. I believe that the method I chose to evaluate this integral is overly simple but mathematically correct and I don't know what I'm doing wrong.
