Find the limit of trigonometric function

Click For Summary

Discussion Overview

The discussion revolves around finding the limit of a trigonometric function, with participants addressing a specific calculus question that involves simplifying expressions. The scope includes conceptual understanding and problem-solving techniques related to limits and polynomial expressions.

Discussion Character

  • Homework-related, Technical explanation

Main Points Raised

  • One participant notes the absence of a clear question and requests clarification on the specific limit being sought.
  • Another participant suggests that the original question may be misleading, indicating that it does not actually involve a trigonometric function.
  • A different participant proposes using polynomial long division to simplify expressions as a potential method for solving the problem.
  • Another suggestion involves using polynomial decomposition to cancel terms in the numerator and denominator.
  • One participant recommends evaluating the function at a specific point to find a constant that makes two definitions of the function equal.

Areas of Agreement / Disagreement

Looks an awful lot like homework to me. Even so, try to simplify your expressions. The question isn't actually asking about a trig function, seeing as there's no trig function there. Either something didn't show up or the question's trying to mislead you with its use of 'theta's. You can use long division of polynomials to simplify these expressions.
 
For the first use the decomposition xn-1=(x-1)(xn-1+xn-2+...1) for both the numerator and denominator and cancel out the x-1 terms.

For the second let x=2 for both definitions of f(x) and find k so that they are equal.
