Then I used Epilog to show two points on the curve. Then we discussed that the two points could be connected by a line and we talked about how the equation of the line would be built using slope intercept form, but the slope we actually wrote it out in terms of the points I chose on the curve. Then I used manipulate to make the difference in the denominator approach to zero but we ran into the problem of diviiding by zero, which led us to use the limit of the slope instead of the slope itself. And once we reached 0 using the limit, we had the tangent line to the curve. Then a couple of weeks later, they came back and I created an animation for te Reimann sums to approximate the area underneath a curve. Much fun and ahhhhs were had.I used Mathematica to tutor some undergrads and the first thing I did was use Mathematica to plot a simple curve. Then I used Epilog to show two points on the curve.
