A point P(x,y) is shown on the unit circle corresponding to a real number t. Find the values of the trigonometric functions at t. x y Upper P left parenthesis font size decreased by 3 negative StartFraction StartRoot 3 EndRoot Over 2 EndFraction comma font size decreased by 3 negative one half right parenthesis font size increased by 1 t (1,0) A coordinate system has a horizontal x-axis and a vertical y-axis. A circle is centered on the origin. A line segment extends from a point plotted on the origin to a point plotted at (1, 0). A second line segment extends from the origin to a point labeled P plotted at (negative StartFraction StartRoot 3 EndRoot Over 2 EndFraction, negative one half). An arc labeled t extends from the horizontal line segment to the line segment that ends on point P in a clockwise direction.
