Evaluate `int0 1e^(2-3x)dx`as a limit of a sum.

Explanation

To evaluate the integral \( \int_0^1 e^{2 - 3x} \, dx \) as a limit of a sum, we can follow these steps:

### Step 1: Define the function
Let \( f(x) = e^{2 - 3x} \).

### Step 2: Set up the limit of a sum
The integral can be expressed as the limit of a Riemann sum. We can divide the interval \([0, 1]\) into \( n \) equal subintervals, each of width \( h = \frac{1 - 0}{n} = \frac{1}{n} \).
