So let us have this differential equation.
00:05
You want to find the cost, which is c, right? but it is a differential equation, which has the derivative being set equal to this guy, right? this is 10.
00:23
So you have this one.
00:29
So what is this differential equation? this is a separable differential equation.
00:34
I can separate it.
00:36
So i'm just going to take the x to the other.
00:39
Side of the equation.
00:42
So this is the x like that, right? then i'm going to integrate both sides because i want to find the c.
00:50
So whenever i integrate one with respect to c, i have c.
00:57
And then this one is a, is two terms, right? so i can integrate a term by term.
01:02
So this one is going to be x squared over 100 plus 10x plus some arbitrary.
01:12
Cost and say b.
01:14
Okay.
01:15
So this is the cost function, right? this is a function that represents the cost...
