Question

1. 1-cos^2 theta/sin theta @shamil98

Answer 1

Yeah this is what I was saying , I don't remember how to do this stuff. Sorry.

Answer 2

No worries, thank you anyways!

Answer 3

1- cos^2 = sin^2
------ ----- = sin
sin sin

Answer 4

don't get what I mean? numerator is 1- cos^2 which is = \(sin^2 \theta\) , then divided by sin \(\theta\) = sin\(\theta\)

Answer 5

That makes sense! Thanks.
What about sin^2x+tan^2x+cos^2x/sec x ??

Answer 6

sin^2 + cos^2 =1 so numerator = tan^2 + 1 = sec^2 then divided by sec = sec

Answer 7

sec^2x-tan^2x/cos+sin^2x

Answer 8

sec^2 = tan ^2 +1 so, numerator = tan^2 +1 - tan^2 =1
we can do nothing with the denominator( if it is as you post) . so the answer is 1/ cos +sin^2
