- There's really a lot of math involved in electrical and electronicengineering.
**How much you do depends on what area of EE (shorthand for electrical and electronic engineer) you do.**

**For example**, there's a lot more abstract math in communication theory and signal processing, and many more**very direct calculation differential equations in circuit theory and systems****design.**

**Circuit theory****at its simplest form is really differential equations, which is basically solving equations involving derivatives**, so you need some**CALCULUS****and****ALGEBRA and TRIGONOMETRY**are fundamental to understanding it. Every basic circuit element (resistor, capacitor, inductor) has arelated current-voltage relation determined by its impedance. This iswhere**COMPLEX NUMBERS**come in.

**If we move on to the****theory of "how" electromagnetism works, we haveMaxwell's equations**. These pretty much form the basis for EE.**They are written in both integral and derivative forms and involve vectors.**So, suddenly, we also have**VECTOR CALCULUS**.

- If we move to
**Communication Theory/Information Theory**, a mathematician named**Claude Shannon**developed a mathematical theory to explain various quantities related to how to communicate between devices.**Communication Theory is used everywhere, from RADAR, to****telephones, to devices within computers. The underlying theory requires at least CALCULUS , some LINEAR ALGEBRA , some MEASURE THEORY, etc**.

**Even wavelets, which have revolutionized signal processing, were discovered by mathematicians early in the 20th century, but not used by engineers until 20 years ago**.

**In general, it is not possible to do EE without math.**

**Each abstract mathematical theorem somehow**

**finds its use in EE**.

Nice information.
