3cos x+4sin x=5" हो,तो "tan x=?

Show that (sin 8x cos x - sin 6x cos 3x)/(cos 2x cos x - sin 3x sin 4x) = tan 2x

(sin 5x + sin 3x)/(cos 5x + cos 3x) = tan 4x

(sin 5x + sin 3x)/(cos 5x + cos 3x) = tan 4x

Prove that (sin x + sin 3x + sin 5x + sin 7x)/(cos x + cos 3x + cos 5x + cos 7x ) = tan 4x

Prove the following : (sin 5x + sin3x)/(cos 5x + cos 3x)= tan 4x .

Write the simplest form of tan^(-1) [( 3 cos x - 4 sin x )/( 4 cos x + 3 sin x) ] , if (3)/(4) tan x gt -1

If cos x.cos y + sin x.sin y = -1 then cos x + cos y is यदि cos x.cos y + sin x.sin y = -1 हो, तो cos x + cos y का मान क्या होगा?

If 3cos x+4cos y=5, then the maximum value of 3sin x+4sin y is

Prove that (sin 5x - 2 sin 3x + sin x)/(cos 5 x - cos x)= tan x
