MathsCasts: First Order Differential Equations: Separation of Variables 2
(Swinburne Commons, 2011)
This screencast illustrates the method of separation of variables for a medium-level first order differential equation: dy/dx=(2-y)/(1+x). Different ways of displaying the solution are discussed.
MathsCasts: First Order Differential Equations: Separation of Variables 3
(Swinburne Commons, 2011)
This screencast illustrates the method of separation of variables for a medium-level first order differential equation: dv/dpsi=v(tan(psi)-mu sec(psi)).
MathsCasts: First Order Linear DEs: Integrating Factors: Part 2
(Swinburne Commons, 2011)
This screencast shows a medium-level example of the solution of a first order differential equation using the integration factors method.
MathsCasts: First Order Linear DEs: Integrating Factors: Part 1
(Swinburne Commons, 2011)
This screencast shows a simple example of the solution of a first order differential equation using the integration factors method.
MathsCasts: First Order Differential Equations: Separation of Variables 4
(Swinburne Commons, 2011)
This screencast illustrates the method of separation of variables for a more advanced (and applied) example with a boundary condition: v dv/dz=-g+kv^2, v(h)=0.
