(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

∫_{0}^{∞}e^{-t}dt

(integral from 0 -> ∞)

2. Relevant equations

3. The attempt at a solution

so far, i have...

∫_{0}^{∞}e^{-t}dt

={-e^{-t}}_{0}^{∞}

= -e^{-∞}- -e^{0}

= 0 + 1 = 1

but looking at a graph, it approaches zero. What am I doing wrong??
