In this assignment we were to create a
worksheet for a student to use to practice
graphing sine waves. We had to include
the worksheet, an answer form and show
common mistakes students make when
graphing (then fix these mistakes). I did
well on this paper and met all
requirements. The worksheet could’ve
been darker. (click on the page to open it)

For this homework assignment we had
practiced graphing a sine wave by
calculating our biorhythms. This page is the
part where we had to graph the wave for
some day that was memorable to see if the
biorhythm matched. The event was an
emotional one, and the emotional wave
almost crossed the critical line on that day,
so it was close.

On this quiz I did pretty well on the front
side. My mistake on the back was that I
graphed the second wave as a cosine wave
and the period was wrong. I knew how to
calculate the period but didn’t graph it
right. (click on the quiz to see the whole
thing)

This is the Unit Test. I
did well on this exam
and even got the
coveted, “N.C.” on my
graphs  The mistakes
I made were not listing
ALL of the x-intercepts
from 0 to 2 pi. I only
listed those from the
first wave. (click on
