All right, we are given y equals e squared all over x times 3x minus 5.
00:17
Now we are going to do the quotient rule.
00:19
There's a quotient in there.
00:22
But before i get started, just remember that e squared is a constant.
00:27
And why am i bringing that up is because the derivative of a constant is zero.
00:31
So when i go to take the derivative using the quotient rule, the derivative of the top is zero.
00:39
That's what i'm trying to get at.
00:42
And you leave the bottom alone.
00:45
And then minus, now you leave the top alone.
00:49
But notice as we do the derivative of the bottom, we have the product rule.
00:53
So you have to do the quantity of the derivative of x, which would be one.
00:58
You leave 3x minus 5 alone.
01:01
And then plus, that's why i put in perfect...
