Handout: Bug on a Circular Track
We talked about using the correct mode when finding the sine or a cosine of an angle with a calculator. Defined radian measurement. Suppose the vertex of an angle θ is at the center of a circle of radius r, and the angle spans an arc of length s.  The measure of the angle θ  in radians is defined as the ratio of the arc length, s, to the radius r (See figure). It follows that an angle of 360Ί spans an arc length of the circumference of the circle, s = 2πr, so this angle has a radian measure of = s / r = 2πr / r = 2π. Consequently 180Ί is equivalent to π radians, which is a handy conversion factor. We looked at converting angles from degrees to radians and vice versa, with and without a calculator. Finally, we looked at some applied questions where we were asked to find the arc length if given the angle (in degrees) and the radius. It is paramount to convert θ from degrees to radians first before applying the relationship s = r*θ, since this only holds if θ is in radians.
Read: Section 6.4
Do:  6.3 -- 1-28, 30-32, 34-42 and prepare for QUIZ 1 on 6.1 and 6.2
Complete Writing Assignment 2: Bug on a Square Track for Wednesday, September 10.

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.
Friday, 9-5 Took QUIZ 2. Introduced SOHCAHTOA and Pythagoras, a perfect pair. Looked at right triangle definitions and applications. 
Do:  Chapter 6 Tools -- 1-10, 19-23, 28, 31

WR3 (Writing Assignment 3): What's My Angle? due Monday, September 15, 2008.  Click HERE.
Wednesday, 9-10

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).  
    (See Section 5.2 and 5.3 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 for y = cos(x).  
    (See Section 5.1 for a review of these topics.)

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

We then looked at the effect of doing both of these kind of transformations to the inside, which causes a horizontal transformation (change to the input), specifically, that the graph of y = Asin(Bx) + k  has period 2π/B.

Due for Friday, September 12.
Read: Section 6.5 and 6.6
Do: Section 6.4 -- 1-26 and prepare for QUIZ 3 over Section 6.3 and Ch 6 Tools (SOHCAHTOA and Pythagoras)

WR3 (Writing Assignment 3): What's My Angle? due September 15, 2008.  Click HERE
Friday, 9-12 Took QUIZ 3 on Section 6.3 and Chapter 6 Tools
One equation says it all: y = Asin(B(x - h)) + k
We explored the effects of  B and h on the graph.
For positive values of B and h: 
the period is 2π/B, the horizontal shift is h units to the right, and the phase shift is Bh to the right. 
In other words, the cycle of the sine curve starts when x = h and ends when x = h + period.
