Due Friday, Sept. 7 Writing Assignment 1: Bug on a Square Track
 Suppose a central angle θ  in a circle of radius r spans an arc of length s. Measure how many radius lengths that the length of the arc is.  This number of radius lengths is the radian measure of the angle θ: we have rθ = s.

Section 7.4
Graphs of the Sine and Cosine (and Outside Changes to the Formula)
Today:  QUIZ 2 over 7.1 and 7.2 and the graph of y = Asin(x) + k (Outside additive and multiplicative changes)

We discussed the domain, range, period, and amplitude of y = sin(x) and y = cos(x) and how these can be determined from the unit circle.

We looked at an outside change to the function, which results in the original function being transformed vertically (change to the output).
1. y = Asin(x) and y = Acos(x) have amplitude |A|.
For A > 0
the graph of y = Asin(x) vertically stretches or compresses the graph of  y = sin(x) by A units.
the graph of y = Asin(x) is a vertical reflection of the graph of y = Asin(x).
Similarly for y = cos(x).

2. y = sin(x) + k and y = cos(x) + k have midline k.
For k > 0
the graph of y = sin(x) + k vertically shifts the graph of y = sin(x) up k units.
the graph of y = sin(x) k vertically shifts the graph of y = sin(x) down k units.
Similarly for y = cos(x).

The first multiplies the output by a quantity; the second adds/subtracts a quantity to the output.

Section 7.5
The graph of
y
= sin(Bx)
(Inside multiplicative change)
For the function y = AsinBx + k
we explored the effects of  B on the period to find that,
for positive values of B, this graph has a period of  2π/B, an amplitude of  |A|, and midline which is y = k.
