SUMMARY

The area between the curves defined by the equations y=e^(5x), y=e^(9x), and the vertical line x=1 is calculated using the definite integral from 0 to 1. The correct integral to find the area is ∫₀¹ (e^(9x) - e^(5x)) dx. The computed area of the region is 870.7489 square units, confirming that the function e^(9x) does not intersect with x=1 but remains finite at e^9.

PREREQUISITES
  • Understanding of exponential functions and their properties

Homework Statement



Sketch the region enclosed by y=e^(5x), y=e^(9x), and x=1. Decide whether to integrate with respect to x or y. Then find the area of the region.

Homework Equations





The Attempt at a Solution



I tried graphing all the lines but they the e^(9x) line never seem to reach x=1 so they don't all intersect.

Surely you know that e^(9*1)= e^9? That's a very large number (larger than 8000) but is still finite! The area of the region is \int_0^1 (e^{9x}- e^{5x})d.
 
Thanks! I got it. Its 870.7489
