First Quadrant Unit Circle

Identify the Positive angle in both radians and degrees that represent point H.

Identify the Positive angle in both radians and degrees that represent point D.

Identify the Positive angle in both radians and degrees that represent point L.

What are the coordinates at point A?

Using θ as a reference angle, mark the triangle sides as Opp, Adj, and Hyp.

Label these on the triangle on your paper.

A central angle in the unit circle measures θ radians, and  $$\sin\theta=\frac{\sqrt[]{2}}{3}$$ . One ray of the angle intersects the circle at (1, 0). For each quadrant, determine if the terminal side of the angle could be in that quadrant. Select Yes or No for each quadrant. Quadrant I ​ (a)   Quadrant II ​ (b)   Quadrant III ​ (c)   Quadrant IV ​ (d)  

Using θ as a reference angle, mark the triangle sides as Opp, Adj, and Hyp. Label these on the triangle on your paper.

Let θ represent an angle on the unit circle, with $$0\le\theta\le\frac{\pi}{2}$$ , such that $$\tan\theta=\frac{\sqrt[]{3}}{3}$$ . Drag and drop the correct answer into each blank. $$\sin\left(3\theta\right)=$$ ​ (a)   $$\cos\left(-4\theta\right)=$$ ​ (b)
