Simplifying Trigonometric Identities Worksheet. Sin𝜃 cos𝜃 cos𝜃 sin𝜃 1 cos𝜃sin𝜃 5. Trigonometric identities are mathematical equations which are made up of functions.
Pythagorean identities in trigonometry worksheets these tailor made high school worksheets precisely deal with expressing the pythagorean theorem in terms of trigonometric functions. Tan 2 θ sec 2 θ 4. Use the trigonometric identities tan x sin x cos x and cot x cos x sin x to write the given expression as tan 2 x cos 2 x cot 2 x sin 2 x sin x cos x 2 cos 2 x cos x sin x 2 sin 2 x and simplify sin 2 x cos 2 x 1.

Worksheet the basic 8 trig identities simplify each expression to a single trig function or number. Both sides should end up being equal so you will not find these on the answer key. Expressions using identities show your work on a separate sheet of paper. 1 tan x cos x 1 2 sec x sin x tan x 2 simplify.
