- Ability to compute Laplace and Fourier transforms and apply the Laplace transform to solve differential equations.
- Ability to compute Fourier series, and Fourier sine and cosine series.
- Ability to find partial and directional derivatives.
- Ability to apply the chain rule to functions of multiple variables.
- Ability to find critical points of a function of two variables and determine their nature.
- Ability to compute double and triple integrals directly and/or by changing the order of integration/changing variables.
- Ability to compute the gradient of a scalar field, understand and apply its geometric interpretation.
- Ability to compute divergence and curl of a vector field.
