[. . . ] ³ Problem Two adjacent angles measure 12¡ 31¢ 45£ and 26¡ 54¢ 38£ respectively. Add the two angles and display the result in DMS format. Round the results to two decimal places. -q$$"""< - 12 %= 1 31 %= 2 45 %= 3 T 26 %= 1 54 %= 2 38 %= 3 < %= 5 < The result is 39 degrees, 26 minutes and 23 seconds. 24 ³ Problem It is known that 30¡ = À / 6 radians. In the default mode, degrees, find the sine of 30¡. Then set the calculator to radian mode and calculate the sine of À / 6 radians. Note: Press - to clear the screen between problems. - %B 1 30 E < q"<%B 1 g P 6 " E < Retain radian mode on the calculator and calculate the sine of 30¡. Change the calculator to degree mode and find the sine of À / 6 radians. %B 1 30 %= < E < q<%B 1 g P 6 " %= 4 E< Trigonometry %B %B displays a menu of all trigonometric functions (sin, cos, tan, sin-1, cos-1, tan-1). Select the trigonometric function from the menu and then enter the value. Set the desired Angle mode before starting trigonometric calculations.

Then calculate angle B and the length of the hypotenuse c. Reminder: 7 7 tan A = -- therefore m±A = tan-1 ⎛ -- ⎞ ⎝ 3⎠ 3 m±A + m±B + 90Ä = 180Ä therefore m±B = 90Ä - m±A c= 3 +7 2 2 A 3 C 7 c B 26 q< $ $ " " < %B 6 7P3"E< 90 U %i < b3FT7F< To one decimal place, the measure of angle A is 66. 8Ä, the measure of angle B is 23. 2Ä, and the length of the hypotenuse is 7. 6 meters. Logarithms and exponential functions %A %A displays two submenus containing the functions log, 10^, ln, and e^. Select the submenu, the desired log function, then enter the value and close the expression with E <. • log yields the common logarithm of a number. • 10^ raises 10 to the power you specify. • ln yields the logarithm of a number ot the base of e (e ≈ 2. 718281828459). • e^ raises e to the power you specify.

To store an operation to op1 or op2 and recall it: 1. You may have to press - if a previous operation is displayed. Enter the operation (any combination of numbers, operations, or menu items and their arguments).
