Question

whrite integration and value of sina + cot a /cosb - cosc + sec b

Answer 1

Answer:

Explanation:

2cosA sinB = sin(A + B) - sin(A - B) ... 2 sinA cosB = sin(A + B) - sin(A - B) 2 cosA sinB = sin(A + B) - sin(A - B) 2 cosA cosB = sin(A + B) = cos(A - B) 2 sinA sinB = cos(A - B) - cos(A + B)
