Explore how to evaluate limits of polynomial, rational, and radical expressions by direct substitution, factor cancellations, and conjugate rationalization to avoid zero denominators.
Explore the derivative through its definition and the alternate form, showing how the secant slope approaches the tangent slope as h→0. Connect average and instantaneous rates of change to derivative.
Explore evaluating limits at infinity by comparing degrees of polynomials, dividing by the highest power of x, and using leading coefficients to determine zero or infinite limits.
Evaluate right- and left-hand limits for the expression (x+3|x+2|)/(x+2) as x approaches -2; the right-hand limit is 1, the left-hand limit is -1, so the overall limit does not exist.
Graph rational functions by canceling common factors to locate vertical asymptotes, analyze left and right limits, and determine horizontal asymptotes and domain.
Compute derivatives from the definition and its alternative form, using examples to find slopes and instantaneous rates, including conjugate tricks for radicals.
This course is all about limit, which is a topic covered in Calculus 1 at the University level.
Once you complete this course, you will thoroughly understand how to evaluate limits given a graph and limits given different functions including trig functions. You will also understand limits related to the definition of the derivative.
