If ` sin A = ( 3 ) /(4) ` calculate ` cos A and tan A `

If sin x + sin y= (1)/(2) and cos x + cos y=1 , then tan (x+y) =______

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

If 3 cot A = 4 , check whether (1 - tan ^ 2 A ) /( 1 + tan ^ 2 A ) = cos ^ 2 A - sin ^ 2 A or not

( cosec A - sin A ) (sec A - cos A ) = ( 1 ) /( tan A + cot A )

Is (sin A )/( cos A) equal to tan A ?

(sin x + sin 3x )/( cos x + cos 3x )= tan 2x

( sin theta - 2 sin ^ 3 theta ) / (2 cos ^ 3 theta - cos theta ) = tan theta

If cos x = tan y , cos y = tan z , cos z = tan x , then the value of sin x is :

In Delta ABC right angled at B if tan A = (1 ) /(sqrt 3 ) then find the value of : (i) sin A cos C + cos A sinC (ii) Cos A cos C - sin A sinC

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
