The question only asks for its radius of curvature.
Is it OK to use the forumula right away?

I wonder if this type of question will come up in real exam papers
Oh, the radius of curvature is much easier since to find the radius of curvature you do not need to find the intrinsic equation of the curve. You need to use the formula

rho = [1 + (dy/dx)^2]^3/2 / [d^2y/dx^2]

And yes, I should of thought there will be a radius of curvature question.

Find dy/dx
Find dΒ²y/dxΒ²
Plug in formula
