Quadrantal angles (0, 90, 180, and 270 degrees), and the values of the sine, cosine, and tangent of each of these angles. From the trig lessons in the Algebra 2 course by Derek Owens.
If the circle is divided into sectors, such that each arc length is equal to the radius of the circle, the central angle in such a sector is called a radian/ rad. So relations between them: 1 grad = 910 degrees and 1 degree = 109grad. 1 rad = 180Ï degrees and 1 degree = Ï180 rads.
