" 23."tan^(-1)((2x)/(1+15x^(2)))

Differentiate tan ^(-1) ((8x)/(1-15x^(2))) w.r.to tan ^(-1) ((2xsqrt(1-x^(2)))/(1-2x^(2)))

y=tan^(-1)((2x)/(1+15x^(2))) find (dy)/(dx)

If y = tan ^(-1) ((2x)/( 1+15x^(2)) ) , and (dy)/(dx) = ( lambda)/( 1+25x^(2)) -( mu)/( 1+9x^(2)) ," then " lambda + mu equal

Differentiate tan ^(-1) ((8x)/(1-15x^(2))) w.r.to x

If x gt 1 then 2tan^(-1)x - tan^(-1) ((2x)/(1-x^(2))) =______.

If I = int tan^(-1)((2x)/(1-x^(2)))*dx then I-2x*tan^(-1)x =

Differentiate w.r.t x tan^-1((2x)/(1+15x^2))

Prove the following: 2tan^(-1)x=tan^(-1)((2x)/(1-x^(2))),-1ltxlt1
