can someone please help me slove these 4 questionss?



1) Sin/ Csc + Cos/ Sec =1


2) sin^2/Sec^2-1 = Cos^2


3) tan/sin =sec


4) 1/1-sin^2=1+tan^2



I really need helpp!

csc = 1/sin

sec = 1/cos

sin^2 + cos^2 = 1

with these identities above, you can pretty much solve all of them. I'll start you off.

1. sin/csc = sin/(1/sin) = sin*sin = sin^2

cos/sec = cos/(1/cos) = cos*cos = cos^2

sin^2 + cos^2 = 1
