how to solve tan^-1 2x/1-x² + cot^-1 1-x²/2x = pie/3

sin inverse sin 3pi/5????

Write the function, cot^-1 (sqrt(1+x^2)+x) in the simplest form

If tan^-1x+tan^-1y+tan^-1z=pie, prove x+y+z=xyz

tan^-1 x + 2cot^-1 x = 2pi/3 find value of x

sin(1/2 cos inverse 4/5) ??evaluate

prove that 2 tan-1 (root of a+b/a-b tn theta/2) = cos -1 (acos theta b/a b cos theta)

simplify

sin-1(sinx+cosx/root 2)where pie

Find x if sin^-1(5/x) + sin^-1(12/x) =pi/2

IF y = sin^-1 (2^x+1/1+4^x) find dy/dx

cot[pi/4 - 2cot^-1 3] =7

sin^-1 x - cos^-1 x = pi/6
