Question

Directions are there.

Convert these to Sin Theta and graph. I just need the sin Theta. Graphing I will worry about, thanks.

Answer 1

Answer and Explanation:

We can find the sine of an angle θ by graphing θ, then finding the y-coordinate of the point of intersection with the unit circle.

`\begin{array}c \underline\theta & \underline{\sin\theta}& 0 & 1 \\ \\\frac{\pi}6 & \frac{1}2 \\ \\\frac{\pi}4 & (\sqrt2)/(2) \\ \\ \frac{\pi}3 & (\sqrt3)/(2) \\ \\\frac{\pi}2 & 0\end{array}`

See the attached image of a unit circle for more coordinates.
