The Biggest Mistake Students Make With Limits to Infinity

Are you consistently losing points on Limits to Infinity because of focusing on the wrong highest-degree terms? If so, you're making the exact same error as 80% of your class.

Did you make this error?

  • The Trap: focusing on the wrong highest-degree terms
  • The Proof: Read this scenario: For lim (x->∞) of (3x^2 + 5x) / (2x^2 - 1), you only care about the highest powers: 3x^2 / 2x^2. The x's cancel, leaving 3/2.

If your logic doesn't match the proof above, you've fallen for the trap. Erase it and start over.
