## anonymous 5 years ago tan^4 h -1 I need to express this in terms of sin h

1. anonymous

$\tan ^{4}(h-1)=\sin ^{4}(h-1)\div \cos ^{4}(h-1)=\sin ^{4}(h-1)\div (1-\sin ^{2}(h-1))^{2}$ is it sufficient or you need to simplify more...?

2. anonymous

or is it $tan^4(h)-1$?

3. anonymous

I don't know if I need to simplify more. Can you? and its (h-1)
