Average value for a function over its entire domain

Click For Summary
SUMMARY

The discussion focuses on calculating the average value of a function over its entire domain. The user initially divides the interval into two segments and computes the average for each segment, seeking confirmation on the correctness of this method. Participants confirm that averaging the two computed averages is indeed the correct approach. Additionally, the discussion touches on the concept of taking the limit as t approaches infinity to determine the average value over an infinite domain.

PREREQUISITES
  • Understanding of calculus, specifically the concept of average value of a function.
  • Familiarity with limits and their application in mathematical analysis.
  • Knowledge of interval division in the context of integration.
  • Basic proficiency in mathematical notation and functions.
NEXT STEPS
  • Study the formal definition of the average value of a function over an interval.
  • Learn about the application of limits in calculus, particularly in evaluating functions as they approach infinity.
  • Explore techniques for dividing intervals and calculating averages in more complex functions.
  • Investigate numerical methods for approximating average values when dealing with non-closed intervals.
USEFUL FOR

Students of calculus, mathematicians, and anyone interested in understanding the average value of functions over specified intervals or infinite domains.

As we know , the average value of a function

i wanted to calculate the average value of a function over its entire domain ( e.g
gif.gif
)

firstly, i divided the interval into 2 intervals

&

and calculated the F_avg for each ,,, is my way correct ? thanks !

yes, then you'll need to average the two averages.

thanks !

but if we assumed t= infinity and take the limit so it'd be :

is it correct ? thanks again !
