Verify the identity: \sin(x + y) + \sin(x - y) = \tan x \cos(x + y) + \cos(x - y) Verify the identity algebraically. 5 cos(x) - 5 cos(x) / 1 - tan(x)) = 5 sin(x) cos(x) / sin(x) - cos(x)). Verify the identity. sin(-x) +...
Example 1: When, sin X = 1/2 and cos Y = 3/4 then find cos(X+Y)Solution: We know cos(X + Y) = cos X cos Y – sin X sin YGiven sin X = 1/2 We know that, cos X = √(1 - sin2X) = √(1 - (1/4)) =√3/2...
