<p>What topics in Calculus do I need to review for Multivariable Calculus? I think most of Calculus wasn't too bad apart from sequences and series, but I don't need to know that, right? :D</p>
<p>I'd say nothing. It's not a difficult course unless you are assigned difficult problems.</p>
<p>Trig identities and knowing how to take integrals of trig functions such as (sin x)^3. Also don't forget polar coordinates. You probably won't need much sequences and series in multivariable.</p>
<p>Brush up all on Trigonometric identities, series/sequences (Taylors), polar/spherical coordinates and basic calculus.</p>
<p>You might not use it all in Calculus 3 but you'd be surprised where these topics pop-up.</p>
