Sketch the graph of the ellipse \(\ds \frac{x^2}{9}+\frac{y^2}{16}=1\) and determine its foci. Let \(C\) be the conic which consists of all points \(P=(x,y)\) such ...

An ellipse is one of four conic sections, i.e. instruments of anguish in math classes. The ellipse obeys the equation: (x/a) ² + ( y/b) ² = 1. In this specific case a = 40, while b = 30. An ellipse is ...
