Tangent lines and areas between curves.

Click For Summary
SUMMARY

The discussion focuses on finding the area between the tangent line of the function y=e^x at the point (1,e) and the curve itself. The tangent line is identified as y=xe, leading to the equation (e^x)/(x)=e for solving x. Participants confirm the need for integration to determine the area between the curves, emphasizing the importance of correctly setting up the equations before proceeding with integration techniques.

PREREQUISITES
  • Understanding of calculus concepts, specifically derivatives and integrals.
  • Familiarity with the exponential function, particularly y=e^x.
  • Knowledge of tangent lines and their equations.
  • Ability to solve equations involving exponential functions.
NEXT STEPS
  • Learn how to compute derivatives and tangent lines for exponential functions.
  • Study integration techniques for finding areas between curves.
  • Explore the Fundamental Theorem of Calculus for area calculations.
  • Practice solving equations involving exponential functions and their intersections.
USEFUL FOR

Students and educators in calculus, mathematicians interested in curve analysis, and anyone looking to deepen their understanding of integration and area calculations between curves.

I have a function:
y=e^x
the tangent line at the point (1,e) would be x*e?

in order to find the area between the tangent line, the y-axis and y=e^x i equate these functions and solve for x?

I got this far

(e^x)/(x)=e
how do i solve for x

Correct!

Thats not exactly it. Do you know how to integrate?
