Evaluate :

`( Cos^3x - Sin^3x ) / ( Cosx - Sinx )`

Evaluate : ( sin^3x + Cos^3x ) / ( sin^2x - cos^2x )

Evaluate : lim_( x -> 0 ) ( tanx - sinx ) / sin^3x

If x = 7.5^(@) then find the value of (cos x - cos 3x)/(sin 3x - sin x)

If sinx - cosx = 0, then the value of (sin^3 x-cos^3 x) is: यदि sinx - cosx = 0 ,तो (sin^3 x-cos^3 x) मान होगा :
