1.) 1/(csc x)(sec^2 x) = ?(adsbygoogle = window.adsbygoogle || []).push({});

a.) 1/(sin x)(cos^2 x)

b.) sin x - sin^3 x

c.) 1/(sin x)(1+tan^2 x)

d.) sin x - (1/1+tan^2 x)

e.) 1+tan^3 x

Here's my work: 1/(csc x)(tan^2 x + 1)

(1/sin x) * ((cos x/sin x)(cos x/sin x) + 1)

So, am I on the right track here? Or do I need to do completely different stuff? I can't seem to find any of those 5 answers no matter what I do...
