`y = x + tan(x), (pi, pi)` Find an equation of the tangent line to the curve at the given point.

The slope of the tangent is equal to the derivative of the equation of the curve at the given point.

`dy/dx = 1+sec^2x`

Slope of the tangent is equal to 2

The equation of the tangent is equal to y-pi=2(x-pi)

That is

`2x-y-pi=0. `
