The values of these ratios can be found using a calculator. Remember, we are working in radians so your calculator must be in radian mode. 3.1.1 Exercise Use your calculator to evaluate the following. Where appropriate, compare your answers with the exact values for the special trigonometric ratios given in the next section. a. sin Ï€ 6 b. tan1 c. cos Ï€ 3 d. tan 4 e. sin1.5 f. tan Ï€ 3 g. cos...Use SOHCAHTOA and set up a ratio such as sin(16) = 14/x (From here solve for X) By the way, you could also use cosine. Method 2 Set up the following equation using the Pythagorean theorem : x 2 =48 2 +14 2 (From here solve for X)

- hypotenuse . adjacent . opposite . H O hypoteneuse opposite. sinÎ¸= = H A hypoteneuse adjacent. cosÎ¸= = A O adjacent opposite. tanÎ¸= = This means that you can work out the size of an angle in a right -angled triangle if you know the lengths of two of the sides, or you can work out the length of any side or angle if you know another angle and a side length: 16 9 x 11 y 5 Trigonometric Ratios
- The inverse trigonometric functions (sin-1, cos-1, and tan-1) allow you to find the measure of an angle in a right triangle. All that you need to know are any two sides as well as how to use SOHCAHTOA.
- meaning to common trigonometry ratios, such as SOH-CAH-TOA. Using these ratios relates Using these ratios relates trigonometric functions to angle measures and lengths relative to either the hypotenuse or radius
