Question 198688: Hello! My name is Aeriin yanu and I am having troubles with proving trigonometric identity. I just learned the lesson today and I don't really understand the lesson. Can you show me how you can solve a trigonometric identity?
ex:
sin square root of 2 phata+ sin square root of 2 phata cotangentsquare root of 2 phata= 1

You can put this solution on YOUR website!
... Start with the given equation.


... Replace cotangent with cosine over sine. Recall: cot%28x%29=cos%28x%29%2Fsin%28x%29


... Multiply


... Cancel out the common terms.


... Use the identity


So this verifies the identity.
