Pythagorean Identity?
cos²ϴ + sin²ϴ = 1
What is:

cos²ϴ + sin²ϴ = 1
The Pythagorean Identity.
Simplify:

(cos²ϴ + sin²ϴ)/cos²ϴ = 1/cos²ϴ
1 + tan²ϴ = sec²ϴ
Simplify:

(cos²ϴ + sin²ϴ)/sin²ϴ = 1/sin²ϴ
cot²ϴ + 1 = csc²ϴ
Express in terms of sin & cos:

1 + tan²ϴ = sec²ϴ
(cos²ϴ + sin²ϴ)/cos²ϴ = 1/cos²ϴ
Express in terms of sin & cos:

cot²ϴ + 1 = csc²ϴ
(cos²ϴ + sin²ϴ)/sin²ϴ = 1/sin²ϴ
