Let p(x, y) be a point on the unit circle, and let t be the arc length from the point (1, 0) to p along the circumference of the unit circle. the trigonometric functions of the real number t are defined as follows: function ratio function ratio sin(t) = y csc(t) = 1 y cos(t) = x sec(t) = 1 x tan(t) = y x cot(t) = x y.
Unit Circle Ck 12 Foundation To define our trigonometric functions, we begin by drawing a unit circle, a circle centered at the origin with radius 1, as shown in figure 2.2.2. the angle (in radians) that t intercepts forms an arc of length s. using the formula s = rt, and knowing that r = 1, we see that for a unit circle, s = t. The radian is the standard unit used to measure angles in mathematics. one radian is the measure of a central angle of a circle that intercepts an arc equal in length to the radius of that circle. one radian: the angle [latex]t [ latex] sweeps out a measure of one radian. note that the length of the intercepted arc is the same as the length of. Definition: circular functions. suppose θ is an angle plotted in standard position and p(x, y) is the point on the terminal side of θ which lies on the unit circle. the cosine of θ, denoted cos(θ), is defined by cos(θ) = x. the sine of θ, denoted sin(θ), is defined by sin(θ) = y. the secant of θ, denoted sec(θ), is defined by sec(θ. More precisely, the sine of an angle t t equals the y value of the endpoint on the unit circle of an arc of length t. t. in figure 2, the sine is equal to y. y. like all functions, the sine function has an input and an output. its input is the measure of the angle; its output is the y coordinate of the corresponding point on the unit circle.
