Thats three values for three different angles in three different functions. Which basically means that one degree can be divided into 3600 little tiny parts. Q. 1) find reference angle (always acute) 2) find the trig function value for the angle (remember special angles) 3) determine the sign Solution: sin s i n = opposite hypotenuse = o p p o s i t e h y p o t e n u s e. sin s i n 45 = AC 8 8 sin45 = AC 45 = A C 8 8 s i n 45 = A C, now use a calculator to find sin s i n 45 45 . In the mid-1500s, the mathematician Franois Vite created tables of all six functions correct to the nearest minute. 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.

(or some multiple of these), respectively. Not familiar with the minute measure in trigonometry? Question 298392: Find, to the nearest minute, the angle whose measure is 3.45 radians. Thats three values for three different angles in three different functions. You can find tables that give function values to the nearest degree and the nearest minute. WebClearly we have 15 degrees, so the remaining 0.6358 is minutes and seconds.
