`tan^(-1)((cosx+sinx)/(cosx-sinx))`

tan^(-1)((cosx+sinx)/(cos x-sinx))

cot^(-1)((cosx-sinx)/(cosx+sinx))

If y=tan^(-1)((sinx+cosx)/(cosx-sinx))," then "(dy)/(dx)" at "x=(pi)/(4)

If y=tan^(-1)((sinx+cosx)/(cosx-sinx)) , then (dy)/(dx) is equal to (a) 1/2 (b) 0 (c) 1 (d) none of these

Simplify: tan^(-1)[(2cosx-3sinx)/(3cosx+2sinx)],2/3tanx> -1

Find the value of tan^-1((sinx+cosx)/(cosx-sinx))
