SUMMARY

The discussion focuses on applying the Trapezoidal Rule to estimate the area under the curve of the function f(t) = t² over the interval [0, 2] with a deltaT of 0.5. The calculation involves dividing the interval into 4 trapezoids, leading to an estimated area of 2.75. This problem is relevant for those preparing for the Fundamentals of Engineering (FE) exam, as it tests understanding of numerical integration techniques.

PREREQUISITES
  • Understanding of the Trapezoidal Rule for numerical integration
  • Basic knowledge of calculus, specifically integration
  • Familiarity with the function f(t) = t²
  • Ability to calculate deltaT and determine the number of trapezoids (n)
NEXT STEPS
  • Study the derivation and application of the Trapezoidal Rule in numerical analysis
  • Learn about Simpson's Rule for comparison with the Trapezoidal Rule
  • Explore error analysis in numerical integration techniques
  • Practice additional FE exam questions involving numerical methods
USEFUL FOR

This discussion is beneficial for engineering students, particularly those preparing for the FE exam, as well as educators teaching numerical methods in calculus courses.

Homework Statement



f(t)=t^2 and [tex]\Delta[/tex]t=.5, where 0<=t<=2 what is the closest? 4, 2.75, 2.67, or 1.33

Homework Equations


deltaT=(a-b)/n

and the formula for the trapezoidal rule when n>1


The Attempt at a Solution



I get n=4 therefore the final answer I get a total area under the function is 5. Does that make sense.

The final answer is wholly dependent on the number of trapezoids chosen, and in this case is 4.
 
Actually I just got it, 2.75 is the answer and if anyone is wondering this is a FE exam question.
