Tangent to an Ellipse
- David Miles
This is an exploration of what is involved when you try to find the general function for the tangent to an ellipse. Since an ellipse is not a function, a piecewise function is required in order to determine the general function of the tangent. It is possible to determine each of the necessary functions individually, but with a little careful thought and consideration of concepts such as symmetry, it is possible to avoid doing this, resulting in a more complex understanding of what is going on.
