When light reflects off a surface, to another point.  This is the shortest distance of any reflection (when the triangles are similar)  We consider a calculus proof of the topic.

2.4 day 2

Euler's method to approximate the value of a function given a differential equation and initial point is explored.

Euler's Method (BC only)

We explore the integral test to determine convergence.  The harmonic series is revisited.

10.5 (BC only)  Integral Test for Convergence

We explore the comparison test and the ratio test to determine convergence.  The area inside polar functions is also explored as well as their slopes.

10.4 (BC only) Convergence and Polar functions

We explore the error bound for Taylor polynomials.
