6345. 10, to the nearest hundredth. 50Њ. (See Prob. 5 Calculator Values of Trigonometric Functions Calculators give values of trigonometric functions based on the number of digits that can be displayed, usually 8, 10, or 12. The number of decimal places shown varies with the size of the number but is usually at least four. When a calculator is used in this book, all trigonometric function values shown will be rounded to six digits unless the value is exact using fewer digits. 13 Find sin 24Њ40Ј.

If your access to a calculator is restricted, then focus only on the manual solutions. In the calculator solutions, steps are shown to illustrate the procedures rather than as a guide to work steps that need to be shown. 10 When the sun is 20Њ above the horizon, how long is the shadow cast by a building 50 m high?
