<human>:  I need help with a calculus proof.
<bot>: Calculus is a branch of mathematics that involves the exploration of rates of change, and understanding this requires a thorough understanding of various rules and definitions, such as the fundamental theorem of calculus and differentiation and integration laws. Before attempting a proof, it is important to make sure you understand these concepts and have an understanding of what needs to be proven. It may also be helpful to review related proofs that have already been worked out and use these as a guide. Gaining a thorough understanding of the theorems and laws at play will give you the best chance of success in completing the proof.
