## Homework Statement

Give the equation of the line tangent to the curve at the given point.

ytan^-1x = xy at (sqrt3,0)

## Homework Equations

## The Attempt at a Solution

Would it be right to do an implicit differentiation or to isolate for y here?

I isolated for y and got y=1/(tan^-1x-x)

deriving: y' = x^2/((1+x^2)(tan^-1x-x))

That's where I'm confused, at the initial differentiation.

Any guidance would be greatly appreciated!
