Question

verify my toyo... please (toyo=mess) integrate sin^5x cos^2x dx

Answer 1

=-1/3cos^3x + 2/5 cos^5x - 1/7cos^7x +c

Answer 2

i used easy sub..

Answer 3

make u = cos(x), du -sin(x) dx then integrate
\[-\int u^2(1-u^2)^2 du\]

Answer 4

yes

Answer 5

sometimes these are a pain, i think this one is ok yes?

Answer 6
