Stationary Points and Optimisation
This is the part where we learn about how we use calculus to solve different kinds of problems. So far we have spent a lot of time learning about how calculus helps us to work out the gradient of given function for any given point. In this section we focus on the points where the gradient is zero. These are called the local maxima and minima and crucial in what we call 'optimisation' where we try to work out how to...
