Solved: Inverse Functions: Triangle Area in First Quadrant

Click For Summary
SUMMARY

The discussion focuses on finding the area of the largest triangle in the first quadrant with two sides on the axes and the third side tangent to the curve y=e^-x. Participants detail the process of determining the equation of the tangent line at a specific point and calculating where it intersects the axes. The area formula derived from this setup is then maximized using derivatives, leading to the conclusion that the maximum area is 2/e.

PREREQUISITES
  • Understanding of inverse functions
  • Familiarity with calculus, specifically derivatives

[SOLVED] Inverse Functions

What is the area of the largest triangle in the first quadrant with 2 sides on the axes and third side tangent to the curve y=e^-x
 
Physics news on Phys.org
just take any value of x and find the equation of the tangent line at that point, and see where it hits the x and y axes. then write a formula for that area, and maximize the formula by taking derivatives. hmmmmm... i think i got 2/e what did you get??
 
yea i got it
thanks
