9-47.

Determine the exact coordinates of a point on the unit circle that has $\text{sin}(θ) =\frac { 1 } { 4 }$.

$\text{Remember that }\text{sin}(\theta)=\frac{\text{opposite}}{\text{hypotenuse}}$

How can you find $\text{cos}\left(θ\right)$, the $x$-value for the coordinate, from $\text{sin}\left(θ\right)$?
