Question

please help thank you :) verify the identity. show work.

cot θ ∙ sec θ = csc θ

Answer 1

I would write all of these in terms of sine and cosine

Answer 2

sec θ = 1 / cos θ and csc θ = 1 / sin θ

Answer 3

simplify the left side to get the right

Answer 4

oh1 cot θ = cos θ / sin θ

Answer 5

okay @welshfella so how do i verify from the first message you sent. or are those two steps it...?

Answer 6

just replace cot and sec on left side with their equivalents in sin and cos and see if you can simplify to get csc theta on right
