Assuming you're not on a dumbphone, there's an icon at bottom right that says 'jsmath'. Click it, then click "quick start" at top left for a link. then click the button at bottom center, then go to the "interactive js math lab" to to hot tests of code.

Or just skip all that bullshit and follow the link:

http://www.math.union.edu/~dpvc/jsMath/jsMath-lab.html

Let's try some fundamentals. whatever string of code you develop above, needs to be enclosed with eqn] [/eqn, or math] [/math works, as well (also fix the braces I left out just there!)

so below, I'll write 2^x, first by itself, then enclosed by <div class="math">, then enclosed by <span class="math">:

2^x

<div class="math"> 2^x </div>

Go here to practice. You can also reach the page via 'jsmath' at the bottom of this page if you're not on a dumbphone:

http://www.math.union.edu/~dpvc/jsMath/jsMath-lab.html

use [eqn ... /eqn] or [math ... /math] to enclose code that you're ready to write. (the above forms are incomplete - enclose braces on the insides!)

Below, let's write 2^x, first by itself, then enclosed by "eqn" "/eqn", then enclosed by "math" "/math":

2^x

Why would you do this? In Asia, at least where I'm from pretty much no questions will be solely on derivatives. We don't have what you call Calc I,II,III but instead we have single and multivariable calculus, where single variable is basically all integrals.
