" 18.If "y=tan^(-1)((3x-x^(3))/(1-3x^(2)))" Find "(dy)/(dx)

If y=tan^-1((3x-x^3)/(1-x^2)) , find dy/dx .

If y = Tan^(-1)((3a^2x-x^3)/(a^3-3ax^2)) then (dy)/(dx)=

If y=tan n^(-1) ((sqrtx(3-x))/( 1-3x) ) ,then (dy)/(dx) =

if y=(tan^(-1)(3a^(2)x-x^(3)))/(a(a^(2)-3x^(2))) then (dy)/(dx)

If y = tan^(-1)((3x-x^(3))/(1-3x^(2))) + tan^(-1) ((4x-4x^(3))/(1-6x^(2) + 4x^(4))) then (dy)/(dx) =

If y=tan^(-1)((3x-x^(3))/(1-3x^(2))),(1)/(sqrt(3))

If y = tan ^(-1) (( 3 x - x^(3))/( 1 - 3 x^(2))) , - (1)/( sqrt(3)) lt x lt (1)/( sqrt(3)) , then find ( dy)/( dx)

y= tan^(-1)((5x+1)/(3-x-6x^(2))) find dy/dx

y= tan^(-1)((5-x)/(6x^(2)-5x-3)) find dy/dx

Find (dy)/(dx) in the following: y= tan^(-1) ((3x-x^(3))/(1-3x^(2))), |x| < (1)/(sqrt3)
