Many important and interesting physical phenomena are modelled by the functions of several variables that satisfy certain partial differential equations. In this chapter, we will learn a few particular partial differential equations that arise in physical sciences such as heat equation, Laplace equation etc.

Although they had a notation for 1 / 2 and 1 / 3 and 1 / 4 and so on (these are called reciprocals or unit fractions since they are 1 / n for some number n), their notation did not allow them to write 2 / 5 or 3 / 4 or 4 / 7 as we would today.

Halley’s Comet follows an elliptical path through the solar system, with the Sun appearing at one focus of the ellipse. Kepler’s third law of planetary motion can be used with the calculus of vector-valued functions to find the average distance of Halley’s Comet from the Sun.
