How do I find the equation of a tangent or normal of a function at a given point?
In this post, we use the derivative in a variety of contexts, including finding the equation of a tangent or normal to a graph of a power function at a given point, as a part of the Prelim Maths Advanced course under the topic Calculus and sub-part Calculating with Derivatives.
The following two videos will assist you in determining the equation of a tangent and normal at any given point.
