Mrs. Cotter groaned, and the rest of the class just gave puzzled looks. TJ tried explaining it again.
“If ‘y’ equals ‘r’ cubed over 3, the derivative of ‘y’ equals ‘r’ squared ‘d•r’, or ‘r’ squared ‘d•r’, which becomes ‘r•d•r•r’.
Har-de-har-har! Get it now?”
“Very nice, TJ,” Mrs. Cotter sighed, “Let’s move on to Jason’s presentation.”
TJ went back to his seat, disappointed that his peers didn’t understand his joke.

'cause when you take the derivative of x^n with respect to x, it becomes n*x^(n-1) which in this case the cube of r becomes a square and its exponent of 3 cancels out the denominator of 3. Only in this case we aren't using the format of dy/dx or dy/dr but putting the dr part on the right side, so the joke works. >:3
