<p>The title says it all. I had a 97 in calculus 3 but I don't remember a thing! I took it a yea and a half ago. When will I use it again? I am a math major.</p>
<p>An argument in favor of not selling your textbooks at the end of the course.</p>
<p>If you’re a math major it’s really probably a good thing that you forgot it. You’re gonna have to relearn it rigorously anyways eventually, after all. Having the “Calculus for Engineers” stuff floating around in your head while you’re trying to learn it the proper way might just end up being more confusing then helpful.</p>
<p>I will need to use it for my upper division multivariable advanced calculus class in the fall. Oh, and the upper division mathematical probability and statistics courses use calc 3 concepts too.</p>
