<p>which class is more difficult would you say? Also, is it true in your opinion that calc 3 is easier than calc 2?</p>
<p>Physics isn’t as procedural as the intro calc sequence, so even if you’re a whiz at integration by parts and chain rule, you have to understand how to define the problem and stay consistent (you’ll understand this better when you get to the elevator problems). Physics I will be a lot harder if you have a weak foundation in manipulating and playing with trig functions (in fact this is true in all physics and engineering course). Even so, neither course is designed to stump you, they are supposed to be your foundation for higher level courses.</p>
<p>As for calc II vs calc III
The sequences/series (i.e. power series, taylor expansions) chapter at the end of Calc II is pretty tricky the first time you see it. Likewise, I found the vector calculus (i.e. Green’s, Stoke’s, divergence theorem) chapter at the end of calc III tricky the first time I saw it. Otherwise I found them to occupy roughly the same amount of study time. </p>
<p>It may not seem like it now, but all the material covered in these classes is important, so do your best to absorb it.</p>
