This video is the start of a new section of the Mathematical Methods (Year 11 VCE Units 1 and 2) course and looks at how we can use the tools we have acquired so far to help us sketch any functions we might be presented with. This video looks at find equations of tangents and normals. I look are recapping how to find the equation of a straight line before heading into the ideas behind what tangents and normals are. I look at how to find equations of tangents and normals using both "by hand" and using the CAS. There are a number of worked examples and all are explained in an easy to understand way.
