यदि (If) `y=(cosx+sinx)/(cosx-sinx)`,तो दिखाएँ कि (show that) `(dy)/(dx)=sec^(2)((pi)/(4)+x)`

Find (dy)/(dx) , when If y = (cos x + sinx)/(cos x - sinx) , show that (dy)/(dx) = sec^(2) (x + (pi)/(4)) .

If y=tan^(-1)""(cosx+sinx)/(cosx-sinx)," then find "(dy)/(dx).

If y=(xsinx+cosx)/(xcosx-sinx) ,then show that dy/dx=x^2/(xcosx-sinx)^2

If y=(1+sinx-cosx)/(1+sinx+cosx), " show that, " (dy)/(dx)=(1)/(1+cos x).

If y=(cosx-sinx)/(cosx+sinx)," then "(d^(2)y)/(dx^(2)):(dy)/(dx)=

tan^(-1)((cosx-sinx)/(cosx+sinx))=pi/4-x

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

If y=(sinx)^(cosx)+x^(sinx) find dy/dx.

If y=|[sinx, cosx, sinx],[cosx,-sinx,cosx],[x,1,1]| then find (dy)/(dx)

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