watch the following animation showing the connection between a wheel turning and two different sinusoidal waves being drawn. pay attention to where the sine wave is when the point is at its highest, notice what part of the graph is shown after one revolution.
What do you notice?

Question 7
7.
Consider a graph where the x-axis signifies the degree, and the graph is showing the y-component of a spot on a wheel as the wheel is turning. The dot starts at (0,1)
if you were to plot the same dot, but instead of using theta as the x axis, you are using time as the x axis, where do you think the graph would hit the x axis?

Question 10
10.
sin and cosine are functions that take angle measurement as inputs. Cos(t) where the units of t are seconds doesn't make a lot of sense. So consider cos(g(t)) if g(x) =2t, where 2 is the rate of speed of the wheel and has the units revolutions/sec, what is the unit of g(x)?

About how long would you say you have worked on this formative so far? Note that there are two very different sections of this homework - graphing and inversing. It may be helpful to spend some time doing homework questions (roughly the first half of the assignment) or work of practicing using your module. Come back to the second half later.
