TEST TOMORROW

Calculus, Feb 15th

We talked about the limit laws. We worked on finding the limits of expressions that would be zero over zero when the value is directly substituted. We had two options today. 1. Factor the numerator and denominator and hopefully cancel the common factor of zero. 2. Use the conjugate for a rational function with square roots and hopefully get a common zero factor that can be eliminated.
