# Solve the followi

deas required to solve the problem:

The general solution of any trigonometric equation is given as –

• sin x = sin y, implies x = nπ + (– 1)ny, where n Z.

• cos x = cos y, implies x = 2nπ ± y, where n Z.

• tan x = tan y, implies x = nπ + y, where n Z.

given,

cosec x = 1 + cot x  .

In all such problems we try to reduce the equation in an equation involving single trigonometric expression.

s { dividing by √2 both sides} . { . } . { cos A cos B + sin A sin B = cos (A - B)}

NE: We can also make the ratio of sin instead of cos , the answer remains same but the form of answer may look different, when you put values of n you will get same values with both forms

If cos x = cos y, impls x = 2nπ ± y, where n Z .  Rate this question :
