2.37 Use a scientific or graphing calculator to compute the following value, accurate to eight decimal places: sin 294.59°.
Different calculators require different rules of syntax. On a basic scientific calculator, you type the angle first and then press the sine button. Graphing calculators usually require you to type the expression in order as you would read it, using parentheses to surround the angle: “sin(294.59).” Make sure that your calculator is in degrees mode; if you do not know how to do this, consult your calculator owner’s manual. If you lost your manual, it is most likely available to download on the manufacturer’s website.
