Question

I dont understand how to find cot, sec, and csc

Answer 1

Explanation:

You just have to take the inverse:

csc θ = 1 / sin θ

sec θ = 1 / cos θ

cot θ = 1 / tan θ

For example:

(a) sin θ = 3/5

cos θ = 4/5

tan θ = 3/4

csc θ = 1 / sin θ = 1 / (3/5) = 5/3

sec θ = 1 / cos θ = 1 / (4/5) = 5/4

cot θ = 1 / tan θ = 1 / (3/4) = 4/3
