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).
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. Read: Section 7.5 Do: Section 7.5 -- 1-12, 21-26 (for practice) Due tonight, Wednesday,

Friday Sept. 7 |
Section 7.5 the graph of y = Asin(B(x-h)) (Inside additive change) |
Today: 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. Read: Section 7.6 and 7.7 Do: Section 7.5 -- 27-31, 37, 38, 44-50 (for practice) Due
