Going back to the basics of trigonometry, you find a great deal of information from a right triangle. The calculator will only tell you what you ask, not necessarily what you need to know. This doesnt even scratch the surface. Functions and their co-functions have the same function values, just for different angle measures. Matt H. When you want the secant of an offbeat angle, such as 47 degrees, you need to resort to some resource such as a table of values or a scientific calculator. All rights reserved.
