IB Mathematics SL – Derivatives, Differentiation, Tangent and Normals

We know that the gradient of a curve at any point is equal to the gradient of the tangent () to the curve at that point.

So about your question we have that

and the gradient of the tangent () at the point is

and the equation of the tangent is given by the following formula

where in your case

and finally the equation of the tangent is

Hope these help!!
