IB Mathematical Studies SL – Calculus, Derivatives, Differentiation, Equation of Tangent
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
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!!
