Creation of this resource was inspired by [url=https://www.geogebra.org/m/S2gMrkbD]this resource[/url] and [url=https://www.geogebra.org/m/MjFgAfBv]this resource[/url] created by [url=https://www.geogebra.org/u/orchiming]Anthony Or[/url]. [br][br]1. Start with Sine. [br]2. Slide the [math]\Theta[/math] bar and observe. [br]3. Slide the segment!, then repeat step 2. [br]4. Reset all the sliders.[br]5 Repeat steps 1 - 3 with Cosine.
[b]Which choice best fills the blank: [br][/b][br]When the point on the unit circle is at angle [math]\theta[/math], the sine graph is the ______ coordinate of the point?
[b]Which choice best fills the blank: [br][/b][br]When the point on the unit circle is at angle [math]\theta[/math], the cosine graph is the ______ coordinate of the point?
The sine graph reaches its maximum value when the angle is at [math]\theta=\frac{\pi}{2}[/math]. What is the maximum value of the sine graph (this is the y-coordinate on the sine graph)?
At what [math]\theta[/math]-value does the cosine reach its maximum value of 1?
In the activity above, the angle doesn't pass [math]2\pi[/math]. This is not because the graph stops, only because it was harder to make the animation keep working. What happens to the sine and cosine graph when theta passes 2π?
The shape of the graph repeats itself because the circle starts everything from the beginning.
