1multiple choice

Evaluate using L'Hôpital's Rule: lim_{x→0} sin ax / (bx), b ≠ 0.

Show answer

a/b

0/0 form. L'Hôpital: (a cos ax)/b. At x=0: a cos(0)/b = a/b.

2multiple choice

Which of the following is NOT an indeterminate form?

Show answer

∞/0

∞/0 is NOT an indeterminate form — it equals ∞ (or −∞). The indeterminate forms are 0/0, ∞/∞, 0·∞, ∞−∞, 0⁰, ∞⁰, 1^∞.

3multiple choice

Evaluate: lim_{x→0} (e^x − 1)/x

Show answer

1

0/0 form. L'Hôpital: eˣ/1 = eˣ. At x=0: e⁰ = 1.

4multiple choice

For which form do we use the method: let y = f^g, take log, find lim(log y), then answer = e^(limit)?

Show answer

1^∞, 0⁰, ∞⁰

The log technique (let y = f^g, take log) is used for exponential indeterminate forms: 1^∞, 0⁰, and ∞⁰.
