Homework Help Overview

The discussion revolves around finding the area between a curve, likely involving integral calculus. Participants are examining the expression of integrals and the implications of constants within them.

Discussion Character

  • Mathematical reasoning, Assumption checking

Approaches and Questions Raised

  • Participants discuss the importance of including differentials in integrals and question the evaluation of a specific integral involving a constant, ln(2). There is also a query about the correctness of a final numerical answer.

Discussion Status

Some participants have provided guidance on expressing integrals correctly, while others are exploring the validity of a numerical result. Multiple interpretations of the final answer are being considered, but no consensus has been reached.

Contextual Notes

There appears to be some uncertainty regarding the final numerical value and the steps leading to it, as well as the treatment of constants in the integral.

I find that it's always helpful (also, it's the proper way to express an integral) to include the differential when writing an integral. In this case the differential is dx .

Your result is correct up to the last step.

What is [itex]\displaystyle\ \int{\ln(2)}\,dx\ ?\ \[/itex] Remember, ln(2) is just a constant

It's 4ln(2) which is approximately 2.77 .
