∫ of (x^2) from 0 to 2 proof w/o using fundamental therom, but w/ Riemann Sums

Click For Summary
SUMMARY

The discussion focuses on calculating the integral of \( \int_0^2 x^2 \, dx \) using Riemann Sums without employing the Fundamental Theorem of Calculus. Participants emphasize the importance of understanding the limit definition involving Riemann Sums, specifically the expression \( \lim_{n \to \infty} \sum f(x)(x_{j}-x_{j-1}) \). A reference to an external resource is provided to aid in grasping the concept, highlighting the need for a detailed proof and understanding of the Riemann Sum approach.

PREREQUISITES
  • Understanding of Riemann Sums
  • Familiarity with limits in calculus
  • Basic knowledge of integral calculus
  • Ability to manipulate summation notation
NEXT STEPS
  • Study the derivation of Riemann Sums in detail
  • Explore the concept of limits in calculus
  • Review examples of integrals calculated using Riemann Sums
  • Investigate the relationship between Riemann Sums and the Fundamental Theorem of Calculus
USEFUL FOR

Students studying calculus, particularly those seeking to deepen their understanding of integration techniques without relying on the Fundamental Theorem of Calculus.

Homework Statement



\int_0^2 x^2 \, dx using true definition involving Riemann Sums (w/o fundamental theorem).

Homework Equations



I don't know what the relevant equations may be, perhaps some type of lim\sum f(x)(x_{j}-x_{j-1})

The Attempt at a Solution



No attempt. Just seeking the long proof for it. Would be grateful for any and all clues to where I could find the long solution to this.

ah thanks, LC, I put that straight to my favorites. I believe that's all I would need to get the concept I'm looking to understand a little better. Appreciate your info.
