I have tried these several times and cannot figure out how to simplify these...
There are 2 problems...I would really appreciate it if someone would look them over and guide me...I am having a very hard time with this unit
Thank you

Hello, aikenfan!
If you're familiar with basic identities, these are simple . . .
(10) Prove: .$\displaystyle \cot^2\!y(\sec^2\!y - 1) \;=\;1$
$\displaystyle \text{We have: }\;\cot^2\!y\underbrace{(\sec^2\!y - 1)}_{\text{This is }\tan^2\!y} \;=\;\cot^2\!y\cdot\tan^2\!y \;=\;(\cot y\cdot\tan y)^2 \;=\;(1)^2 \;=\;1$
