-Find the equation of a line passing through the origin so that the sine of the angle between the line in quadrant $\mathrm { I }$ and the positive $x$-axis is $\frac { \sqrt { 3 } } { 2 }$.
A) $y = \frac { \sqrt { 3 } } { 3 } x$
B) $y = x$
C) $y = \sqrt { 3 } x$
D) $y = \frac { \sqrt { 3 } } { 2 } x$

Quizplus · Accepted Answer

The sine of the angle between the line and the positive x-axis is equal to the slope of the line when the line passes through the origin. Since $\sin(\theta) = \frac{\sqrt{3}}{2}$ corresponds to an angle of $60^\circ$, and the tangent (slope) of $60^\circ$ is $\sqrt{3}$, the equation of the line is $y = \sqrt{3}x$.
