`3cos (3x+4) - 4sin(4x +5)`का समाकलन कीजिये -

3cos x+4sin x=5

cos 4x = sin 3x

What is the value of [(sin7x- sin5x)/ (cos 7x + cos 5x)]- [(cos 6x-cos 4x)/ (sin 6x + sin 4x)] ? [(sin7x- sin5x)/ (cos 7x + cos 5x)]- [(cos 6x-cos 4x)/ (sin 6x + sin 4x)] का मान क्या है?

int ((cos x) ^ (4)) / ((sin x) ^ (3) ((sin x) ^ (5) + (cos x) ^ (5)) ^ ((3) / (5)) ) dx

If 3sin(x y)+4cos(x y)=5,t h e n(dy)/(dx)= (a) -y/x (b) (3sin(x y)+4cos(x y))/(3cos(x y)-4sin(x y)) (c) (3cos(x y)+4sin(x y))/(4cos(x y)-3sin(x y)) (d) (sin^2(a+y))/(sina)

If 3sin(x y)+4cos(x y)=5 , then (dy)/(dx)= (a) y/x (b) (3sin(x y)+4cos(x y))/(3cos(x y)-4sin(x y)) (c) (3cos(x y)+4sin(x y))/(4cos(x y)-3sin(x y)) (d) none

(cos 4x +cos 3x + cos 2x )/( sin 4x + sin 3x + sin 2x)= cot 3x

(cos 4x +cos 3x + cos 2x )/( sin 4x + sin 3x + sin 2x)= cot 3x

(cos 4x +cos 3x + cos 2x )/( sin 4x + sin 3x + sin 2x)= cot 3x
