Calculus can be an intimidating subject. For many students, even the name sounds intimidating. The truth is that Calculus is based on a few very powerful principles and once you fully understand those principles all of the additional topics naturally follow. Most Calculus textbooks begin the subject with a nauseating discussion of limits and then proceed to the introduction of a derivative which is one of the core topics in Calculus. This DVD series begins the discussion immediately with the concept of the derivative without any math at all and spends some time ensuring that this concept is solidified. Limits are used to explain the derivative via example problems beause that is how they are defined, but you will not be presented with endless lectures on abstract math topics that are not directly related to the core topics of Calculus. All of the other topics are taught in the very same manner, relying on the power of learning by working fully narrated example problems in a step-by-step fashion.
