6 trig functions of 3 4 5 triangle-Section 43 Right Triangle Trigonometry 301 The Six Trigonometric Functions Our second look at the trigonometric functions is from a right triangle perspective Consider a right triangle, with one acute angle labeled as shown in Figure 426 Relative to the angle the three sides of the triangle are the hypotenuse, theInverse trig functions arcsine, arccosine, and arctangent Now let's look at the problem of finding angles if you know the sides Again, you use the trig functions, but in reverse Here's an example Suppose a = 123 and b = 501 Then tan A = a/b = 123/501 = Back when people used tables of trig functions, they would just look up

Section 54 The Other Trigonometric Functions In the previous section, we defined the sine and cosine functions as ratios of the sides of a right triangle in a circle Since the triangle has 3 sides there are 6 possible combinations of ratios While the sine and cosine are the two prominent ratios that can be formed, there are four others, andIn a 345 triangle = ABBCCA we know CA = 5 is the hypotenuse and its opposite angle B is 90 degrees Sin(90 degrees) = 1 so in the sin rule we have 5/1 = 4/sin(A) = 3/sin then Sin(A)=4/5 and sin=3/5 We also know A C = 90 so sin=3 /5 = 06 means (with an inverse sin calculator) that C= and then A=4 LawofSines c a b Figure 34 Sample triangle Example 5 is suggestive of a general rule called the LawofSines Specifically,given the sample triangle in Figure 34 with sides a,b, and c opposite the angles α,β, and γ respectively,the Law of Sines states that
