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?

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?

at 2π

after 1 minute

when the wheel had made a complete rotation

when the wheel had made a quarter rotation

If you want to talk about how fast a wheel is moving, what units do you use?

miles per hour

meter/second

revolutions/seconds

seconds

if a wheel is moving at 1 revolution per second, how many degrees has that wheel moved in 0.5 seconds?

45°

90°

135°

180°

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)?

degrees

radians

revolutions

seconds

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.

Ok, have you rested your working memory?

y=x^2 is not a one to one function, but we have a sortof inverse for that function anyway - what do we do to "undo" the squaring function.
