00:00:00.000 --> 00:00:03.750
Here is the problem: derivative of e to the power x.

2
00:00:04.200 --> 00:00:08.147
Find the derivative of e to the power x with respect to x.

3
00:00:08.947 --> 00:00:16.575
Exponential rule: d by d x[eᵘ] equals eᵘ times u prime.

4
00:00:17.025 --> 00:00:18.569
Combine and simplify.

5
00:00:19.369 --> 00:00:23.525
So the answer is f prime of x equals e to the power x.

6
00:00:23.975 --> 00:00:36.943
The derivative is built from the outside in: sums split into terms, constants factor out, products and quotients use their rules, and every composite function multiplies by the derivative of its inside (chain rule).

00:00:37.743 --> 00:00:44.338
Cross-checked numerically against an independent symbolic differentiator at 8 sample points, which checks out.
