You don't truly see the power of calculus until you have handled Fourier transforms and differential equations (beams bending, heat distribution, cable vibration/dampening, stress, etc.). It's fairly amazing how well you can understand the physical universe with these tools. Linear algebra is definitely more abstract, which, in my opinion, makes it more difficult. Using the word "algebra" has little meaning to me, as many mathematical concepts can be used to arrive at a solution. From what I have learned, the *conclusion* is more important than the *method* to arrive at the conclusion. Then again, I'm in engineering, so I'm likely biased. We aren't given the opportunity to see many derivations, which can be very beautiful.

I'd rather not force this into a thread about personal thoughts though (seems rather menial).
