Hey there, I'm learning about trig identities and I'm having trouble with this question. 

Its asks:

Prove the trig identity, and you must use the trig identities taught (formula sheet). Show all steps.

cosx = sinxtan?xcof'x
Transcribed Image Text:cosx = sinxtan?xcof'x
Reciprocal Identities: Quotient Identities: Pythagorean Identities: 1 csc = tane =- sine sin? 0 + cos? 0 = 1 sine cos o tan? 0 +1= sec? e 1 coso sec 0 cot 0 = cos 0 sine 1+ cot? 0 = csc? 0 1 cot0 = tan0 Double Angle Identities: Compound Angle lIdentities: cos 24 = cos? A- sin² A = 2 cos? A-1 =1-2 sin? A cos(A + B) = cos A cos B – sin Asin B cos(A – B) = cos A cos B + sin A sin B sin(A + B) = sin Acos B + cos Asin B sin 2.4 = 2 sin A cos A sin(A – B) = sin A cos B – cos A sin B
