As a chemical engineering major, how far into math should I go. We are required to do calc 1-3 and elementary differential equations. But upon speaking to my professor I was told that I might find more differential equations classes, linear algebra and possibly some analysis class to be useful. What is the opinion of those people who are already engineers or who simply know. How far into math should I go? Just as a point I have no aversion to math and am not trying to find a cutoff where math is useless because all math I am sure is somewhat useful, but what math courses would I find to be immensely useful.
