# Interactive video lesson plan for: Limits at Infinity Rational, Irrational, and Trig Functions READ DESCRIPTION

#### Activity overview:

EXAMPLES Rational Functions 7:57 14:45 17:25 Irrational Functions 24:25 33:02 39:15 Trig Functions 47:01 47:40
As I lectured I misspoke a few times, at about 2:29 I should have said vertical distance, 8:20 we are looking for the highest degree of the denominator, and at 23:07 x greater than n like it was written.
In the third example at 17:25, you should divide by the largest degree in the denominator, so I should be dividing by x^3 or multiplying by 1/x^3 here. Luckily my final answer is still correct. I would have had 0/1=0. I incorrectly say in this lesson that the square root of x squared is x. The square root of x squared is the absolute value of x.
