Lecture Details :

I discuss and solve an example where we calculate the partial derivative of $arctan (y/x)$ with respect to $x$. The method of solution involves an application of the chain rule. Such an example is seen in 1st and 2nd year university mathematics.

Course Description :

Topics covered will include important aspects of applied mathematics used in engineering, such as: multivariable calculus; vector calculus; differential equations; Laplace transforms; Fourier series.
