Right Answer – Wrong Question Continuity or continuity “on its domain”?

Asymptotes

Fun with Continuity

Right Answer – Wrong Question. What does “Continuous on its domain” mean.

Far Out  A fun limit, but best saved until after students can find maximum values and points of inflection.

Limits

In an ideal world, I would like to have all students study limits in their pre-calculus course and know all about them when they get to calculus. Certainly, this would be better than teaching how to calculate derivatives in pre-calculus (after all derivatives are calculus, not pre-calculus).

Limits are the foundation of the calculus. Continuity, an important property of functions, depends on limits. All derivatives and all definite integrals are limits. For AP Calculus students need a good intuitive understanding of limits, what they mean, and how to find them The formal (delta-epsilon) definition is not tested and need not be taught, however, do not feel that you have to avoid it. If your students can handle it, let them try.
