Angle conversion, so how to change between an angle in degrees and one in terms of ππ (unit circle radians); and The trigonometric functions of the popular angles. Let's start with the easier first part. The most important angles are those that you'll use all the time: 30°=π/630...
Further let be the set of points on the unit circle with finite –adic expansions of their coordinates and let be the set of angles of the points . Then is an additive group which is the direct sum of infinite cyclic groups and of the finite cyclic group . If in case of the point...
We have now found the cosine and sine values for all of the most commonly encountered angles in the first quadrant of the unit circle. The table below summarizes these values.Angle 0 π6π6, or 30° π4π4, or 45° π3π3, or 60° π2π2, or 90° Cosine 1 √3232 √2222 ...
trigonometry functions applied to an angle are cosine, sine, and tangent. These are the three functions that we apply to find the coordinates of a given angle on the unit circle. Using all the information above, you will be able to find the cosine and sine values of the important angles....
