Calculus can be one of the most exciting branches of mathematics that there is, but it can also be one of the harder ones to understand and learn. A good course in Calculus would begin with a study of limits and continue through to the integral and applications thereof. Many first time Calculus students do not understand the underlying foundations of the derivative and the integral, and their connections to other areas of study, primarily Physics. So, for those wayward souls having difficulty with some concepts of Calculus, please look below to find that much needed help.
