Question

Trigometric simplifications help?

Answer 1

\[\int\limits \sin ^{2} xdx\]

Answer 2

you should try writing it as \[\sin^2 (x) = \frac{1}{2}-\frac{1}{2}\cos(2x)\] then interfrat the sum term by term and factor out constants to get started!!

Answer 3

integrate* (spelling mistake :O)

Answer 4

if you get stuck i can attempt to show you step by step if you like

Answer 5

please can you?

Answer 6

\[F(x)= -cosx +\frac{ 1 }{ 2 }\cos ^{2}x+c\]

Answer 7

is that right?

Answer 8

your close !

Answer 9

sort of :O

Answer 10

write sin2 as:integrate the sum term by term and factor out constants for the integrand cos(2x), sub u=2x and du=2dx the int of cos u is sin u sub back in u then =
