Number of solution of the equation |cos x| = sin x for x [ 4 π , 4 π ]  will be equal to 4 times the number of solutions of the same equation for x [ 0 , 2 π ]

Graphs of y = |cos x| and y = sin x are as shown below.

Hence, two solutions of given equation in [0, 2]

 total of 8 solutions in [4, 4]

sin (A + B) = sinA cosB + cosA sinB

sin (A - B) = sinA cosB - cosA sinB

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

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

tan (A + B) = (tanA + tanB) / (1 - tanA tanB)

tan (A - B) = (tanA - tanB) / (1 + tanA tanB)
