Solving Limits Analytically Limit Laws, Direct Substitution, Dividing out, and rationalizing the numerator
Methods of Finding Limits • Numerically = in a table • Graphically = on a graph • Analytically = using algebra/equations
Solving Limits Analytically • Limit Laws • Direct Substitution • Dividing Out • Rationalizing the Numerator
Limit Laws Let b, c , n > 0, and Then:
Limit Laws Let b, c , n > 0, and Then: 4. 5.
Direct Substitution This method of solution can only be used when the functions are: • Polynomial functions • Rational functions with nonzero denominators • Positive Integer Radical functions (square, cube, quartic, etc roots) • Trigonometric functions • Composite functions of above
Example Find the limit for each function.
Dividing Out When you have a rational function where you can “divide out” a factor.
Rationalizing the Numerator When you have a rational function where the numerator has a sum or differenceand a radical.
