WebNote that the tangent of a right angle is listed as infinity. That’s because as the angle grows toward 90°, it’s tangent grows without bound. It may be better to say that the tangent of 90° is undefined since, using the circle definition, the ray out from the origin at 90° never meets the tangent line. Exercises 29.
