Exponents and Logarithms Answers

11 HL Trigonometric Equations and Identities Test

On Friday, November 24th we’ll have a test on trigonometric equations and identities (this includes all of the material we’ve covered on trigonometry, but does not include the sine and cosine rules, which will come on the next test).

To prepare for this test, I suggest you look at the review sets in Chapters 10, 12, and 13, and also have a look at Chapter 7 in the Pearson textbook.

12 SL Stationary Points

In class we defined a stationary point, and noted that a stationary point may be a local maximum or a local minimum. There is, however, a third option, as illustrated by the function \(f(x)=x^3\) when \(x=0\). While the function does have a stationary point at \(x=0\), it is neither a local maximum, nor a local minimum, instead, it’s called a point of inflection.

Read Section 16C, then try questions 1 and 2ac in Exercise 16C before our class on Wednesday.

Use the laws of logarithms to answer the following questions for the start of our next class on Thursday.
