12 HL: Calculus: Reviewing the Basics

Complete the following questions before the start of class on Tuesday, August 25th.

Complete:

  • Review Set 16A (all questions)
    For question 6 you can use the rule that \[\textrm{If } f(x)=x^n, n\neq 0, n\in \mathbb{R}\textrm{, then }f'(x)=nx^{n-1}\] rather than using first principles. (Also, remember that “from first principles” is the way that some textbooks will indicate that they want you to start from the definition.)
  • Exercise 17A questions 2, 3, 6, 7cdef, 8, 11

(If you finish this and want to work ahead, continue reading Chapter 17.)

12 HL The Ratio Test

Complete the following questions before our next class.

Use the ratio test to determine the convergence or divergence of the following series.

  1. \[\sum_{n=1}^\infty \frac{n^3 3^{n+1}}{4^n}\]
  2. \[\sum_{n=1}^\infty \frac{n^{10}}{10^n}\]
  3. \[\sum_{n=1}^\infty \frac{n^n}{n!}\]
Click for a hint to question 3.
Consider the definition of \(e\).

From the Haese book, complete Exercise K.3 question 1.
