What type of math is used in electrical/electronic engineering?
Take as many math courses as you possibly can. In reality, much of the work in engineering is done with computers and CAD so most of the time the math is done for you but you still need to understand everything behind it in order to analyze problems. And sometimes you have to write your own CAD tools because what you meed doesnt exist so take some computer science courses too. As for specific courses – trig, calculus, linear algebra, differential equations, etc.
