Apologies for the delayed posts while I was getting my computer fixed… I’m working on catching up now Topics: • Discussion of exponential functions in applications. The solutions to the quiz are posted here. • How to find the coordinates … Continue reading →

There will be a quiz tomorrow. The topics will be exponential function application, and finding the amplitude, period, and phase shift for a sine or cosine function.

Topics: • Quick review of the three definitions of the trig functions – we need to use all three from time to time, but the Unit Circle definitions are the most important! • Important facts that follow from the definitions: … Continue reading →

Topics: • Discussion of some homework problems (Exercise 15.1 parts 1, b, c) Here is something that came up in (c): * We need to know how to interpret what the calculator is telling us. In particular, when the result … Continue reading →

(After Test 3)   Techniques we will need for applications of exponential functions: Solving for an unknown exponent Example: find x if Solution: take the logarithm of each side. Any base will do. We will use the natural logarithm. by … Continue reading →

Here is the Thinking Strategically Post-Test Survey: it will be useful for you to complete this even if you did not complete the pre-test survey (as it will help with your future test preparation) ThinkingStrategicallyPostTestSurvey   Here are the solutions … Continue reading →

Topics: • Review of finding x- and y-intercepts for various kinds of functions (the basic principle being the same) To find the x-intercepts (which are the roots of the function) you set the function = 0 (namely, y=0). To find … Continue reading →

Test 3 is scheduled for Wednesday 15 November, the first hour or so of class. Here is the survey for you to use to plan how to make best use of the resources available to you: this is for your … Continue reading →

Topics: • Graphs of logarithmic functions: transforming the basic log function graphs (see Session 5, section 5.2 to review the transformations) • Finding the equation of the asymptote, the domain, the x-intercept, and the-y-intercept (if it exists) for the transformed … Continue reading →
