1. It has two main parts: Differential and Integral Calculus

2. In mathematics, Newton shares the credit with Gottfried Leibniz for the development of the differential and integral calculus.

3. When Feynman was 15, he taught himself trigonometry, advanced algebra, infinite series, analytic geometry, and both differential and integral calculus.

4. By convention, these applied methods are beyond simple geometry, such as differential and integral calculus, difference and differential equations, matrix algebra, mathematical programming, and other computational methods.
