<p>Do students with heavily quantitative majors (engineering, economics, physics) usually take Calc III?</p>
<p>How much might mastery of Calc III help such students in their fields? Or, would mastery of Calc II be sufficient?</p>
<p>How much does Calc II differ from Calc III?</p>
<p>Calculus III is interchangeable with Multivariable Calculus is usually a required class for an engineering degree. I’d check with your university and looks at the required courses. </p>
<p>Calc II differs from Calc III in the sense that they are two different courses. Just like Calc I and II are two different courses.</p>
<p>A quick breakdown of calc 1-4:</p>
<p>1: single variable differentiation
2: single variable integration
3: multivariable and vector based differentiation
4: multivariable and vector based integration</p>
<p>Of course there is some overlap and some other stuff thrown in their as well (like infinite series in calc 2). For many engineering fields, I’d think that the full calculus sequence since usually most in real life situations have more than one variable to work with, plus the fact we live in a 3d world, not a 2d plane.</p>

<p>Engineering and physics majors are generally required to take calculus 3 or multivariable calculus. Economics majors might not be, but those intending to go on to PhD study in economics are recommended to take it, plus additional math like linear algebra, differential equations, real analysis, probability, and statistics.</p>
