Theres a few...(adsbygoogle = window.adsbygoogle || []).push({});

Write each expression as a single trigonometric ratio or as the number 1.

1) sint+(cott)(cost)

2) (sec x)(sin^2x)(csc x)

For number one I went like this:

sin t + ((1/cot)(cos/1))

sin t + (cos t/cot t)

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

(sin t cos t)/1 + (sin t cot t)/1

But then I get stuck.

For number 2 I went like this:

(secx)(sin^2x)(cscx)

(1/cosx)(sin^2x/1)(1/sinx)

sin^2x/(cosx)(sinx)

But then I got stuck again.
