Sign of 90 degree angle
WebIn trigonometry we use the functions of angles like sin, cos and tan. It turns out that angles that have the same reference angles always have the same trig function values (the sign may vary). So for example sin(45) = 0.707. The angle 135° has a reference angle of 45°, so its sin will be the same.
