They're called exact equations because the total differential is also called the exact differential. It's exact because everything adds to a constant. The actual idea behind exact DE's is that there are two independent variables and no dependent variables, hence F being constant. This means that dF is always zero, but dx and dy are always changing but add up to zero exactly. When bprp did the calc one differentiation, he should have implicitly differentiated with respect to t, as if t was the independent variable, and then asked, "What's this t? I don't see any t's. I know that x and y are supposed to be functions of t, BUUUT, what if there was no t?" Then you multiply by dt to get rid of the dt's and, bam, an exact equation.

This man teaches better than many High END profile teachers on those Ivory League Universities. Yes those are top researchers but teaching should be as good as research. Besides all of these theorems deserves a nice Proof. There could be a series of videos proving all these theorems and derivations.

In the derivative dy/dx it should be noted that x and y can have only values that are on the actual curve. How is this handled? If (x,y) coordinate value that is not on the curve is substituted to the dy/dx equation, then is that actually a derivatives that is resulted? Then derivative exists also outside the curves line?
