Both trigonometry and Euclidean geometry are used across the board in mechanical and civil engineering, not to mention anything periodic, like wave forms. (One of my undergraduate majors was robotics and artificial intelligence.)  So your affection for trig is a good thing.

Math induction is something that I think is important because it is very useful for proving that recursive algorithms actually work and that sequential systems actually behave as expected. It is used all over mathematics.
