Question

integrate
sin(x)/sin(4x)

Answer 1

ok tell me how can i initiate

Answer 2

maybe you can initiate by expanding sin (4x)
\[\sin (4x)\implies 2\sin (2x)\cos (2x)\]
\[\implies 2(2\sin x \cos x)(\cos^2 x - \sin ^2 x)\]
\[\implies 4\sin x \cos x (\cos^2 x - \sin ^2 x)\]
does that help?

Answer 3

yes then in denominator
i hav
4cos@cos2@

Answer 4

ok i got it take sinx as t
and then diff it wrt x
ok thank u

Answer 5

welcome
