Separable Differential Equations

A series of free Calculus 2 Video Lessons from UNSW - University of New South Wales, Sdyney.

Lec8: Partial derivatives and integration.
A lecture on partial derivatives and integration. Plenty of examples are discussed and solved to illustrate the ideas. Such concepts are seen in first year university mathematics courses.

Lec9: Intro to Separable Differential Equations
A lecture that introduces differential equations and show how to solve separable differential equations. Plenty of examples are discussed and solved. The ideas are useful in modelling phenomena.

Lec10: Linear and Exact Differential Equations.
This lecture shows how to solve linear and exact differential equations. Techniques include: integrating factors; the product rule and the chain rule. Such equations are important in modelling and are seen in first year university mathematics.

Homogeneous first order ordinary differential equation
I discuss and solve a "homogeneous" first order ordinary differential equation. The method involves a substitution. Such an example is seen in 1st and 2nd year university mathematics.

Mixing problems and differential equations.
A simple example known as a "mixing problem" is discussed and modelled via differential equations. Such ideas are seen in 1st year university.
