The Sinusoid Mini Project

Standards: Pre-Calculus 4.6,4.7

We are going to make a slide show/movie like the one above. You will be doing this by making a PowerPoint and drawing graphs of functions. You will describe what is going along with the equation. For example, The sine function amplitude increased: f(x)= 5sin(x). Now this video will not flow as well as the one above, but if you make it flow better and have the final screen show the new correct equation and graph, extra points could be awarded.

Directions 1. Open up PowerPoint and make a graph. It doesn't need a grid, but should have dimentions of at least, -2pi: x: 2pi, andn -2: y: 2.



2. Make a sinusoidal function using the curvy line application in PowerPoint. I suggest when doing this that you click each high point, zero, and low point, to make it the best sinusoid possible. When you are done with your sinusoid, double click the end point.

3. At the bottom of each slide write the equation of the sinusoid. Remember the equation is f(x)= a+b[sin/cos(cx+d)]. Also for an extra side note: For radians) sin(0) = 0, sin(pi/2)=1, sin(pi)=0, sin(3pi/4)=-1, sin(2pi)=0, cos(0)=1,cos(pi/2)=0,cos(pi)= -1, cos(3pi/4)= 0, cos(2pi) = 1.

4. You must have at least 6 slides, 3 sinusoids, and adjust a,b,c,d of the equation at least once.

5. Along with writing the equation at the bottom of each slide, remember to write how you are adjusting the sinusoid. (Changing the amplitude, the phase displacement, etc.)

6. You can make smoothish transistions by just making the slides change on their own accord after 3 seconds.

7. Remember if you make it more smooth, there might be extra points! There might be also if you make it a movie in MovieMaker or iMovie.

8. Be creative, show off how smart and talented you are!

9. I will be around helping out and trying to explain what you need to do. Once you are finished, email your PowerPoint to me.

10. See Rubric to see how I will be grading you. [] Example media type="youtube" key="ZI22-SfST08" height="344" width="425" align="center"
