**trigonometry Finding angles using arctan - Mathematics**

Math.Tan takes the angle in radians and gives the ratio (in your case) CA/AB. You need Math.Atan (or better, Math.Atan2, as given in one of the answers below). – iamnotmaynard Mar 8 '13 at 22:03... Find the numerical value of the tangent. Using the middle chart, you see that the numerical value of the tangent of 60 degrees is . Find the sign of the tangent. Because a 300-degree angle is in the fourth quadrant, and angles in that quadrant have negative tangents (refer to the preceding section), the tangent of 300 degrees is. To try your hand at working with radians, find the cosecant of
