Question

what is 1/1+cot^2 theta expressed as a single trigonometric function?

Answer 1

1+cot^2 = ?

Answer 2

my answer sheet says sin^2. i just need to know how to get there

Answer 3

@nincompoop

Answer 4

well you need to know what the equivalent of 1+cot^2

Answer 5

and that's sin^2.
how did you get to the answer? I missed alot of the material, as I had an emergency, so I'm really confused

Answer 6

is 1+cot θ = sin^2?

Answer 7

I don't think so

Answer 8

oh sorry, it's 1-cos^2

Answer 9

1+ cot^2 θ = ccs^2 θ
and then
1/csc is the same as sin
therefore,
1/csc^2 θ = sin^2 θ

Answer 11

1/(1 + (cos^2 x)/(sin^2 x) = (sin^2 x)/(sin^2 x + cos^2 x) = sin^2 x
