Calculus is a branch of mathematics considered a gateway to higher-level mathematics. The origins of calculus can be traced to ancient Egypt, where methods involving calculus were used to find the volume of non-standard shapes. Modern calculus has its foundation with the work of Isaac Newton and Gottfried Wilhelm Leibniz in the seventeenth century. Calculus has many applications in physics, economics, and astronomy. Yet the question, “What is Calculus used for?” is still always asked by students.
