# Equation of the tangent

## Equation of the tangent

The curve C has equation $x=8y\tan&space;2y$

The point P has coordinates $\inline&space;\left&space;(&space;\pi&space;,\frac{\pi&space;}{8}&space;\right&space;)$

(a) Verify that P lies on C

(b) Find the equation of tangent to C at P in the form ay=x+b, where the constsnts a and b are to be found in terms of $\pi$
