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
