SUMMARY

The discussion revolves around finding the antiderivative F(x) of the function f(x) = -x sin(πx) - 3cos(πx) with the condition F(0) = 0. The user expresses frustration over their inability to solve the integral, while another participant highlights the importance of posting in the correct forum section and suggests that integration by parts may be necessary for the term -x sin(πx). The conversation emphasizes the need for clarity in problem-solving approaches to facilitate effective assistance.

PREREQUISITES
  • Understanding of antiderivatives and definite integrals
  • Familiarity with integration techniques, particularly integration by parts
  • Knowledge of trigonometric functions and their integrals
  • Basic problem-solving skills in calculus
NEXT STEPS
  • Practice integration by parts with functions involving products of polynomials and trigonometric functions
  • Review the integration of trigonometric functions, specifically -3cos(πx)
  • Explore the concept of definite integrals and their applications
  • Study common mistakes in calculus problem-solving to improve clarity in communication
USEFUL FOR

Students studying calculus, particularly those struggling with integration techniques, as well as educators looking for examples of common pitfalls in problem-solving discussions.

let F(x) be the antiderivative of the function
f(x) = -x sin (pi*x)-3cos(pi*x)
such that F(0) = 0.Find F(1/2)

ive tried so many differnet ways for this and i still can't get it can someone please help
 
Well, so far you have done just about everything wrong! First, you posted this in "Learning Materials" rather than in the homework section. Second, although you say you have "tried so many different ways", you have shown none of them so we can't say what you might have done wrong.

Are you having difficulty integrating -3 cos(pi x)? Or is it -x sin(pi x)?

The first should be easy and the second not to difficult to do using integration by parts.
