In this video I cover how to find the derivative of a function at a single point. This is done by using limits and the difference quotient. Remember that when working with the difference quotient usually a lot of work must be done to simplify it before the limit can be found. For more videos please visit http://www.mysecretmathtutor.com

Before I met Jonathan, I was struggling through most of my STEM classes because I was simply not studying properly. He taught me all kinds of new study habits that would help me to save time, raise my grades, and lower my stress. Jonathan was specifically tutoring me in vector calculus and is an amazing tutor on the subject. You will walk away from a lesson with a game plan knowing exactly what you need to do before your next session with him or before your next exam in order to do well in the course. I highly recommend him as a tutor.

We know about functions where exponents are raised to different variables, to produce quadratics, cubics, quartics, and so forth. But what about when the variable itself is an exponent? This is called an exponential function, and they are important for modeling things like population growth and other real-world scenarios. Let’s learn about them!
