## Homework Statement

A circle has the parametric equations:

x=1+2cos[tex]\theta[/tex]

y=3+2sin[tex]\theta[/tex]

dy/dx= -1/tan[tex]\theta[/tex]

Find the tangent equation at the point with parameter [tex]\theta[/tex]

## Homework Equations

y-y1=m(x-x1)

## The Attempt at a Solution

I've tried putting dy/dx in as the gradient and then x1 and y1 as the parametric equations but i seem to come up with some really long equation that I am sure isn't right.

Any help at all would be greatly appreciated. Many thanks.
