y=tan^(-1)(4x)/(1+5x^(2))+tan^(-1)(2+3x)/(3-2x)

If y=tan^(-1)((4x)/(1-5x^(2)))+tan^(-1)((3+8x)/(8-3x)) , then (dy)/(dx) is :

If y=tan ^(-1) ((4x)/( 1+5x^(2))) +cot ^(-1) ((3-2x)/( 2+3x)),then (dy)/(dx)=

If y=tan^(-1).(1)/(1+x+x^(2))+tan^(-1).(1)/(x^(2)+3x+3) upto +tan^(-1).(1)/(x^(2)+5x+7)+….+2n terms (AA x ge0), then y(0) is
