<p>diff eq is after calc 3 right? is it relatively easier than calc 1, 2, or 3 or is it still considered a weedout course?</p>
<p>Diff Eq/Math 216, the “engineering major course”, only prerequires Calc II. You don’t need III first. It is significantly easier than II and III. Just as easy as I.</p>
<p>Diff eq/Math 316, the “math major course”, which prerequires Linear Algebra/Math 217 (which in turn prerequires Calc III) is fairly harder than 216 as significant theory/proofs are involved. Still not too bad though.</p>
<p>MATH 216 was pretty easy. Just go to class, write down everything on the board, then refer to it as needed for your homework.</p>
<p>Everything was pretty simple, but I wasn’t a huge fan of Laplace transforms</p>
<p>calc 4 is pretty easy compare to calc 3, but it’s still curved, so do really well on exams because the avg tend to be really high due to their easiness.</p>
<p>great thanks 
I want to take diff equations now.</p>
<p>do you need to know any concepts from calc 3 to take diff eq or is differential eq completely different?</p>
<p>Not that I remember. Partial DiffEq would require some knowledge from calc 3. But DiffEq just requires basic knowledge of differentiation (calc 2), and then throws some new topics in along the way.</p>
