# C in Multivariable?

<p>I did alright on Line Intergrals but once it came to Spherical Coordinates and Jacobian I got murdered. I'm scared of Differential equations now cause of this. My GPA lowered cause of it.</p>

<p>I just want to know whether I can still be an Engineer eventhough I'm choking on the higher math classes.</p>

<p>Will I ever use Jacobian and stuff like that?</p>

<p>Multivariate calc generally doesn't appear in Differential Equations. Once you hit the higher maths, they kinda split apart. You'll get some overlap (set theory in discrete and linear, vectors in linear and multivariate, eigenvectors in linear and diff eq, etc), but for the most part the classes go off in different directions. So, while some topics may be covered by multiple classes, you shouldn't be in too much trouble.</p>

<p>You will need your Calc 2, so don't forget that. Partial fractions and integration by parts come up in multiple classes, and generally you're not getting a review of them.</p>

<p>Alternatively, ask someone at your school what the course covers. Different schools teach different material, but surely a friend or a professor can tell you if multivariate is going to try to eat you.</p>

<p>Short answer: You should be fine. Ask someone who's taken the class at your school if you're still worried.</p>

<p>I agree with the above poster. I don't think you have much to worry about. When you take differential equations you will find out what you really learned in Calculus II because you will have to use many different integration techniques. But most of that latter stuff in Calculus III won't come back to haunt you.</p>

<p>So, my general notion coming out of multi myself (and having seen the first third or so of differential equations during self-studying) is that multi was calculus-geometry while differential equations is calculus-algebra. I know that's a gross oversimplification, but I'm actually looking forward to differential equations over multi for this reasons (I have a hard time imaging shapes in my heads). I hope the same applies to you.</p>

<p>I just barely got an A in Multivariable, but it was definitely the most challenging class in the math sequence for me, and I think a lot of other people agree. I found Diff Eq SO much easier - just on a totally different level than MV. It's so much less conceptual - much more of a class about methods than theory. I think a lot of people have this issue with MV - it's quite tough, so I wouldn't worry to much about the C. I think you'll be just fine - definitely for Diff Eq, and most likely for engineering as well.</p>
