These activities are done in degrees.

10/18/2018 I added 2 assignments that work at socrative.com

Included in this zip folder are 17 PDF files. 12 files are assignments and 5 are for instruction. A brief description of each:

Instruction file A is a 22 page file over the period of a sinusoid. There are 6 formative questions in the file.

Instruction file #1 is a 17 page file with a graphic organizer printable for notes. The emphasis is the vertical shift or centerline of the sinusoid. There are 5 formative assessment questions in the file.

Instruction file #2 is a 17 page file. The emphasis is the vertical stretch or height of the sinusoid. There are 5 formative assessment questions in the file.

Instruction file #3 is a 16 page file. The emphasis is the horizontal stretch relative to the period of the sinusoid. There are 5 formative assessment questions in the file.

Instruction file #4 is a 30 page file. The emphasis is the horizontal shift or phase angle of the sinusoid. There are 8 formative assessment questions in the file.

Assignment #1 is 4 graphs and the student must give:

1. The vertical shift (centerline)

2. The vertical stretch (height)

3. The period

4. The horizontal stretch factor

5. The phase angle if a transformation of y=sinx

6. The phase angle if a transformation of y=cos x

It is on 1 page for easy printing.

Assignment #1A is like #1

Assignment #1B is like #1

Assignment #2 is 20 graphs. 10 are for cos and 10 for sin. The student writes an equation of each graph. It is on 2 pages for easy printing.

Assignment #3 is like #1. However the phase angle for y=-sinx and y=-cosx are also required. This assignment is on socrative and the share number is included in the file. It is on 1 page for easy printing.

Assignment #3A is like #3.

Assignment #3B is like 3.

Assignment #3D is like #3.

Assignment #4 is 10 graphs. 5 are for sin and 5 are for cos. The student is asked to write an equation of each graph. It is on 1 page for easy printing.

Assignment #5 is a 20 question multiple choice assignment. The student uses transformations to select the best graph. It is on 1 page for easy printing.

Assignment #6 is 10 graphs. 5 are for -sin and 5 are for -cos. The student is asked to write an equation of each. It is on 1 page for easy printing.

Assignment #7 is 4 graphs. The student must write 4 equations for each graph as a transformation of:

1. y=sinx

2. y=-sinx

3. y=cosx

4 y=-cosx
