Hello,

Now note that

Substitute u=cos(x)and

INTEGRAL of: 27(sin(x)/(cos(x))^3

Im suppose to have my answer in terms of tangent. Which messes me up because usually i would do a trig substitution to cancel out the sine. If its not possible to express it in terms of tangent then what is it in terms of sine and cosine.

get your answer and it'll be ok if you want to transform into tangent, use the identity 1=sinē(x)+cosē(x)

then transform sin(x)/cos(x)=tan(x)

but it's not necessary
