The value of sin 83 degrees can be calculated by constructing anangleof 83° with thex-axis, and then finding the coordinates of the corresponding point (0.1219, 0.9925) on theunit circle. The value of sin 83° is equal to the y-coordinate (0.9925). ∴ sin 83° = 0.9925. ...
Find sin270∘ Explanation: On the trig unit circle, sin (270) = sin (90 + 180) = - sin 90 = - 1 sin(720) https://www.tiger-algebra.com/drill/sin(720)/ Calculate the value of the sin of 720 ° To enter an angle in radians, enter sin(720RAD) sin(720 °) = -4.8984254152...
The value of sin 18 degrees can be calculated by constructing anangleof 18° with thex-axis, and then finding the coordinates of the corresponding point (0.9511, 0.309) on theunit circle. The value of sin 18° is equal to the y-coordinate (0.309). ∴ sin 18° = 0.309. ...
The sine of an angle, θ, in a right triangle is defined as the ratio of the opposite side to the hypotenuse. This concept extends to arbitrary angles in the unit circle, where the sine function represents the y-coordinate of a point on the circle. 正弦,通常简写为sin,是一个三角函数,...

Trigonometry and the Unit Circle: The trigonometric functions may be related to as functions of the x and y values of points on the unit circle where the angle is made by the radius and the positive x-axis. In particular,y=sinθandx=cosθwill be found on the unit circle. ...

A commonly used law in trigonometry which is trivially derived from the sine definition is the law of sines: The sine function can be extended to any real value based on the length of a certain line segment in a unit circle (circle of radius one, centered at the origin (0,0) of a...
解析 1 Graph θ = (π )2 in standard position on the same axes as a unit circle with center(0.0); its terminal ray intersects the circle at (0.1). The y-coordinate of the poin of intersection represents the sine value of θ = (π )2, so sin (π )2=1....
