We will do an application problem related to a sinusoidal graph. We will use the graph to model the amount of daylight in a specific location in the U.S,

We will graph equations of the form y=Asin(B(x + C)) +D and identify the amplitude, period, frequency, wavelength, phase shift, and vertical shift of the base function y = sin x.

We will use the unit circle to define radian. We will use radians to graph trig functions. We will use trig functions to model real quantities that are periodic.

We will finish the topic of sequences and series by relating geometric sequences to compound interest. We will compare the notation for sequences to the notation for compound interest.

We will write a formula for the nth term of a geometric sequence. We will also use the formula to find the sum of the terms of a geometric sequence. We will relate geometric sequences to compound interest and the calculus concept of an integral.

Exponent operations and simplification involving various roots. Preparation/practice for Unit
Quiz . Writing square roots , cube roots etc, in exponent form. Products and quotients with square roots and cube roots. During today's review for the Unit Quiz on Exponent Operations and various Roots to simplify, James worked very productively and diligently. His grades have been steadily increasing during the past several weeks.

After a brief review we will study the notation of sequences so that we can use technology to graph sequences and evaluate series. We will use a graphing calculator and desmos.com.

We will do example problems from a precalculus book based on what we have discussed previously.

We will continue the study of sequences by doing examples of recursively defined sequences.

We will review what we have completed involving sequences and series. Today we will define sequences recursively, study infinite sequences, and find sums of infinite geometric sequences when possible.
