This is another video in the Further Maths series dealing with Financial Mathematics. It's the turn of perpetuities and how we can use the Financial Solver and the CAS to help us work with perpetuities. We have already dealt, in a previous video, with the idea of annuities where the money from an investment is paid out each month and eventually runs out. A perpetuity lets you invest money and (effectively live on the interest indefinitely!). So, crack out the CAS and let's get some learning done.
