Solved: Prove the following: a. 2sin^2(45°-A)=1-sin 2A b. 2 sin^2(90°-A)=1+cos 2A C. 2cos^2(45°-A) [Math]

सिद्ध कीजिए `(cos (90^(@)-A)sin (90^(@)-A))/(tan(90^(@)-A))=sin^(2)A.`

Example 8 - If sin (A - B) = 1/2, cos (A + B) = 1/2, find A

SOLVED: Prove the following identities: 1 = cos^2A + 5tanA sin^2A tan^2A + cot^2A = 2cosec^2A cosA + sinA sec^2A + tan^2A = cosA sinA 1 = cos^2A + sin^ 2A 8) =

Sin(90-A) /1-tanA+cos(90-A) /1-cotA=sinaA+cosA

prove the following with diagram 1) sin(90-A)=cosA 2)cos(90+A)=-sinA 3)sin (180+A)=-sinA - pm8v54ww
