Learning Outcomes

Almost all equations in engineering are fundamentally differential equations. To put it short, a differential equation is an equation, which includes derivatives. The solution of a differential equation is a function, which satisfies the equation. In the first part of this course, the student learns to solve the most common types of differential equations. Laplace’s transformation maps a differential equation onto an algebraic equation, which can be solved relatively easily. The second part of this course introduces series, especially the power series. Almost any function relevant to engineering can be represented as a power series. Selected terms of the series constitute a polynomial, which yields an approximation to the function near a given point. Power series allows an easy way to approximate the value of a function without a computer or a pocket calculator. With the series one can also perform, e.g., numerical integrations.
