We can now put our triangle into the Cartesian plane and investigate the trigonometric ratios of other key angles like 120 150 210 240 300 330 etc 9 G Examples Ex 1 Determine the sine of 495 The document reviews trigonometric ratios and their application in solving right triangles particularly focusing on special angles It includes exercises for computing numerical values of trigonometric expressions involving these special angles
We can now use the special triangles in Figures 5 and 6 to calculate the trigonometric ratios for angles with measures 30 45 and 60 or 6 4 and 3 Figure 5 Figure 6 Special Triangles These are listed in Table 1 Trig ratios don t depend on the size of the triangle so we can let the sides be any convenient length 2 You ll see why 2 is useful in a minute 1 Divide the triangle into 2 equal right angled triangles
