So just using a graph and calculator, you can get a pretty good visualization on what's happening here, where you have x cubed over 2 minus x.
00:17
And so let's see if i'm missing anything.
00:19
Looks pretty nice there.
00:21
And what you can do is use implicit differentiation to y times.
00:27
I mean, right, y crime is equal to.
00:31
And on the right side, you have the quotient rule where you take the derivative.
00:34
Of the top, leave the bottom alone, minus.
00:40
Now you take the derivative of the bottom, which is negative one, leave the top alone all over the denominator squared.
00:51
Now this won't show up on graph, but i can solve for y prime by taking this thing, and i would probably clean it up just a little bit, like change that minus and negative one to be just a plus.
01:07
You might be able to simplify even more, but i need to divide that 2y over this 2y...
