Question

Help me?
(csc y + cot y)(csc y - cot y)/csc y

Answer 1

1. FOIL the numerator:

csc ^2 y - csc y cot y + csc y cot y - cot ^2 y / csc y

2. The csc y cot y subtracts out, leaving us:

csc^2 y - cot ^2 y / csc y

3. The numerator is an identity, which equals 1:

1 / csc y

4. This is a reciprocal identity, which becomes:

sin y

Does this help?

Answer 2

Awesome. I got most of it, except for that last step. Thanks so much. :) Is this one about the same? vvv

Answer 3

csc(theta)cot(theta)/sec(theta)

Answer 4

@Rookies21

Answer 5

its cot^2 .
Try writing out the csc(theta) and Cot(theta) and Sec(theta) in terms on sin and cos theta...
it helps alot...

Thank you so much! God bless you! :D
