Use the (x,y) coordinates in the figure to find the value of the trigonometric function at the indicated real number, t, or state that the expression is undefined.
sin5π/3
The value of sin(5π/3) can be determined by evaluating the y-coordinate of the point on the unit circle corresponding to the angle 5π/3.
In the figure, we can see that the point on the unit circle corresponding to 5π/3 has coordinates (-√3/2, -1/2). Therefore, the value of sin(5π/3) is -1/2.
