On the unit circle what is sin

WebSine is "opposite over hypotenuse" (the SOH of SOHCAHTOA). When we draw the triangle inside a unit circle the hypotenuse is automatically 1 at any angle. That means the sine of an angle is simply the length of the "opposite" leg of the triangle (opposite / 1). If you make the circle radius = 2 it makes both O and H twice as long, but the ratio ... WebThe relationships between the graphs (in rectangular coordinates) of sin(x), cos(x) and tan(x) and the coordinates of a point on a unit circle are explored using an applet. Definitions 1- Let x be a real number and P(x) a point on a unit circle such that the angle in standard position whose terminal side is segment OP is equal to x radians.(O is the …

WebIn mathematics, a unit circle is a circle of unit radius—that is, a radius of 1. Frequently, especially in trigonometry, the unit circle is the circle of radius 1 centered at the origin … Web180 + 45 = 225 degrees. 180 + 60 = 240 degrees. Finally, and this is the toughest part, it’s important to memorize the x and y coordinates (or (cos θ, sin θ) values) of the 30, 45, and 60-degree angles in the first quadrant. If you can do this, you can easily find the values for the rest of the important angles on the unit circle.
