On the unit circle what is sin

WebThere's nothing wrong with the original answer of 1/sqrt (2), but this is just more 'proper', if you will. 2) Arcsin is restricted to the 1st and 4th quadrant because the value of sine goes from all possible values that way. Think about the unit circle. In quadrants 1 and 2 sin will have the same value. 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 ...

WebSin 0 Degrees Using Unit Circle. To find the value of sin 0 degrees using the unit circle: Draw the radius of the unit circle, r to form a 0° angle with the positive x-axis. We also know that for the sin 0°, the angle 0° corresponds to the point (1, 0) on the unit circle (as it is a point on the unit circle present on the x-axis). Web14 de jun. de 2024 · A unit circle has a center at (0, 0) and radius 1. The length of the intercepted arc is equal to the radian measure of the central angle t.
