Let's use the definition of Riemann sum for the integral: $$\int_0^M e^{-x}dx=\lim_{N \to \infty} \frac{M}{N} \sum_{n=0}^N e^{-\frac{nM}{N}} $$ If we are familiar with the geometric sum formula (here $e$ is just a number and all we need to know is $e>1$), we can write: $$\sum_{n=0}^N e^{-\frac{nM}{N}}=\frac{1-e^{-M \frac{N+1}{N}}}{1-e^{-\frac{M ...
5 sie 2024 · To find the integral of e −x from 0 to infinity, we set up the integral as follows: \int_{0}^{\infty} e^{-x} \, dx. We will use the fact that the integral of e −x over these limits can be evaluated using the fundamental theorem of calculus. First, we find the indefinite integral of e −x: \int e^{-x} \, dx = -e^{-x} + C. Now, we evaluate ...

Improper integrals are introduced and the integral of e^-x from 0 to infinity is discovered and explained.
To build on kee wen's answer and provide more readability, here is an analytic method of obtaining a definite integral for the Gaussian function over the entire real line: Let $I=\int_ {-\infty}^\infty e^ {-x^2} dx$.
16 kwi 2015 · $$I_n = \frac {-x^n} {e^x} + \int_{0}^{\infty} \frac {n x^{n-1}} {e^x}\,dx$$ The value inside the integral is $nI_{n-1}$, so all I'm left is to get the limit of the first term as x ranges from 0 to infinity.
