Okay, first step here, let y equal x, e to the x.
00:08
And then what we do, we take log base e of both sides.
00:14
So you put ln here and ln here.
00:20
Then we have lny, third law of logs.
00:26
This comes down in front.
00:30
So we have e to the x times ln.
00:35
Lnx, just algebra.
00:40
Then i differentiate both sides.
00:43
So on the left is implicit on the right as normal.
00:49
So i'm doing d by d x of the left hand side and d by d x of the right hand side.
01:02
Now on the left, i can write this as dy by d x, d x, d by dy of lny...
