The "Unit Circle" is a circle with a radius of 1. Being so simple, it is a great way to learn and talk about lengths and angles. The center is put on a graph where the x axis and y axis cross, so we get this neat arrangement here.
Sine, Cosine and Tangent Since the radius is 1, we can read sine, cosine and tangent just from the x and y coordinates. 2 Now look at the unit circle and find the point \ (P\) designated by that same angle in radians. 3 Measure the horizontal (signed) distance that gives the \ (x\)-coordinate of point \ (P\).

The ANGLE α is the LENGTH OF THE ARC in the unit circle for the angle α in degrees. Read this sentence until you understand it. It is critical.
The height of the point is the value of the sine function of the angle α. Rounded to 3 decimal places, how much is α=? What is the α in degrees? Which is on the x. 12 graph and make a dot at the top of it.

Note: Since this point is above the x-axis in the unit circle, the corresponding point on the function graph should also be above the x-axis.

Learn sine, cosine, tangent values, radians vs degrees, and memorize key angles. A radian (rad rad) is the angle (\theta θ) which subtends an arc equal to the length of the radius of a circle and the SI unit of angles. The angle of a circle is 2\pi 2π radians.
Radians are defined slightly differently, as this diagram shows: For a circle of radius r, if we draw an arc of length r, then the angle at the centre will be 1 radian. The angle of the sector shown is 1 radian. Symbol for radians Radians are sometimes abbreviated to rad, so we would write 2 radians as 2 rad.
