Due Tuesday, Jan. 29 - Writing Assignment 2: What's My Angle?
Class meeting Topic Assignment
Tuesday, Jan. 22 Section 7.4 Graphs of Sine and Cosine 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 the same holds for y = cos(x).
(See Section 6.1 and 6.2  for a review of these topics.)

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 the same holds for y = cos(x).
(See Section 2.4 for a review of these topics.)

The first multiplies the output by a quantity; the second adds/subtracts a quantity to the output.
For the function y = Asinx + k or y = Acosx + k
we explored the effects of  A and k to find that this graph has an amplitude of  |A|, and midline which is y = k.

Due: Thursday, Jan. 24
Optional:
Section 7.4 -- 1-24, 26-30, 34-38 and Chapter 7 Review 14a, 14d, 19-24, 51, 52, 69-71 and read Section 7.5

Thursday, Jan. 24 Section 7.5
The graph of

= sin(Bx)
(Inside multiplicative change)

For the function y = AsinBx + k or y = AcosBx + k

QUIZ 3 over Section 7.3 and Chapter 7 Skills Refresher

Due Tuesday, Jan. 29 - Writing Assignment 2: What's My Angle?

Class meeting Topic Assignment
Tuesday, Jan. 29 Section 7.5
For positive values of
A, B, h, k, and φ
we explored the graph of
y
= Asin(B(xh)) + k or
y = Asin(Bxφ) + k
where h is the
horizontal
shift to the right and
where φ = Bh is the
phase shift to the right.
Today:  QUIZ 3 over 7.3 and Chapter 7 Skills Refresher
Continued Section 7.5. If given a graph, find the midline, period, amplitude, and the horizontal and phase shifts. When specifying horizontal and phase shift, include whether it is regular sine or cosine (or upside down versions of these), whether it is shifted left or right, and by how much.

Due Tuesday, Jan. 29

Due Tuesday, Feb. 5
• 11:59 pm: E-HW 03 Section 7.4 and 7.5
• Writing Assignment 3: Trig Graphs
Thursday, Jan. 31 Building Closed. If Indiana Daylight Hours vs. Time were modeled as an upside down cosine graph (see below)
but over an interval of [0, 2π],
then today marks a special point between the Winter Solstice and the Vernal Equinox
which roughly correspond to π/6,
or one twelfth of the period.

"Groundhog Day" and the European feast called "Candlemas" are other popular ways this moment is marked..

In tribute to "π/6 Day", the Purdue Fort Wayne campus has given all students the day off to celebrate
(despite what you have heard about some other reason like a winter storm).

To enjoy the festivities, find the amplitude, midline, and formula of this graph and
use it to determine today's number of daylight hours.
