Prove that :- (tan5x + tan3x)/(sin5x - cos3x) = 4cos2x cos4x

(tan5x+tan3x)/(sin5x-cos3x) = 4cos2x cos4x

Prove that: tan5x+tan3x/tan5x-tan3x = 4cos2xcos4x

tan 5x + tan 3x/tan 5x -tan 3x= 4 cos 2x cos 4x.​
(tan5x+tan3x)/(sin5x-cos3x)=4cos2x cos4x
tan5x-tan3x-tan2x = tan 5x - tan 3x
tan2x-tan3x-tan5x=tan2x tan3x tan5x
cos 4x + cos 3x + cos 2x sin4x+ sin3x + sin2x = cot 3x.
