Exam 2

Question 1

Indeterminate forms you can use L’Hospital’s Rule on

Answer 1

0/0, ∞/∞, ∞/-∞, -∞/-∞

Question 2

0 * ∞ or 0 * -∞

Answer 2

rewrite as g(x)(1/f(x)) or f(x)/(1/g(x)) to get into form you can use L’Hospital’s Rule on

Question 3

∞-∞

Answer 3

Use algebra (common denominators) to rewrite in a form you can use L’Hospital’s Rule on

Question 4

0^0, ∞^0, or 1^∞

Answer 4

Use natural logarithms to rewrite in a form you can use L’Hospital’s Rule with. Let y=the indeterminate form–>take limit of both sides. —> Don’t forget to relate y back to the original limit
