SUMMARY

The discussion focuses on the integration of the expression (e^(2t) + e^(-2t) + 2)^(1/2) with respect to t. Participants suggest transforming the expression into a perfect square to simplify the integration process. The solution involves recognizing that the integral leads to the equation a = exp(t) - exp(-t), which then requires finding the inverse of a. The discussion highlights the utility of algebraic manipulation in solving complex integrals.

PREREQUISITES
  • Understanding of calculus, specifically integration techniques.
  • Familiarity with exponential functions and their properties.
  • Knowledge of algebraic manipulation, including completing the square.
  • Experience with inverse functions and logarithmic properties.
NEXT STEPS
  • Study integration techniques, particularly integration by parts and substitution methods.
  • Explore the properties of exponential functions and their transformations.
  • Learn about completing the square in algebraic expressions.
  • Research inverse functions and their applications in calculus.
USEFUL FOR

Students and professionals in mathematics, particularly those studying calculus and algebra, as well as educators looking for step-by-step integration techniques.

For part of a problem, how would I integrate:

(e^2t+e^-2t+2)^(1/2) with respect to t

I have no idea..., but I've tried integration by parts to start...
 
Physics news on Phys.org
can you transform e^2t+e^-2t+2 into a perfect square?
 
Ok, i see now. Thanks.

I have another problem now... I found the solution to be a=exp(t)-exp(-t) and I need to find the inverse of a. Taking the ln of each side didn't help at all.

multiply by exp(t) and bam you got a quadratic!
