Double Derivative Calculus Test - Nature of Stationary Points

In this video, we look at classifying the nature of stationary points using the double derivative calculus test. A stationary point occurs when the first derivative is equal to zero, but whether this stationary point is a local maximum, local minimum or a stationary point of inflection rem

AlgTop4: More on the sphere

This lecture continues our discussion of the sphere, relating inversive geometry on the plane to the more fundamental inversive geometry of the sphere, introducing the Riemann sphere model of the complex plane with a point at infinity. Then we discuss the sphere as the projective line ove
