I recently posted about some trig equations, now i'm doing some HW on trig proofs, i got the first couple trig proofs, but had trouble with the last two.(adsbygoogle = window.adsbygoogle || []).push({});

Here are the two problems (attached). For the first one, i can't even get started. i have some ideas, but i can't find out how to get the right side (1/(1+secθ). For the second one, i simplify the right side for cosθ/sinθ, but i'm not sure if thats right (i can't get the right side to anything like that). any help would be appreciated, thanks!
