From these, we can derive the double-angle formulas for sin(2α), cos(2α), and tan(2α):In addition, the cos(2α) formula has two alternate but common forms. By utilizing the identity sin2(α) + cos2(α) = 1, we can also derive the two formulas:...
A right angle is an angle of exactly 90 degrees, such as the corners of a square. It is also a part of a right triangle, which is necessary for some basic trigonometry formulas to work(such as sohcahtoa).Answer and Explanation:
