[. . . ] Calculates the reciprocal of a value. b %c %a Examples 5FT4GD2T1E< 10 G M 2 < b 49 < b3FT2G4 < 21 6 %c 64 < D 2 T 6 E %a < Pi g À ≈ 3. 141592653590 for calculations. À ≈ 3. 141592654 for display. Example À 2Vg< r Note: Classic mode displays calculations with À as a decimal approximation. ³ Problem What is the area of a circle if the radius is 12 cm?g V 12 G 2 < r The area of the circle is 144 À square cm. The area of the circle is approximately 452. 4 square cm when rounded to one decimal place. 22 Angle menu %= %= displays the choice of two submenus that enable you to specify the angle unit modifier as degrees (º), minutes ('), seconds ("), radian (r), or convert units using 4DMS. You can also convert between rectangular coordinate form (R) and polar coordinate form (P). Entries are interpreted and results displayed according to the angle mode setting without needing to enter an angle unit modifier. If you specify an angle unit modifier from the Angle menu, the calculation is performed in that angle type, but the result will be given in the angle mode setting. Examples RAD q"< - %B 1 30 %= 1 E < DEG q< ÄÅÆ - 2 g %= 4 < 1 8 5 %= 5 < 4DMS 23 Convert polar coordinates (r, q)=(5, 30) into rectangular coordinates. Then convert rectangular coordinates (x, y) = (3, 4) into polar coordinates. R ¶P -q$$"" < - %= " 3 5 %` 30 E < %= " 4 5 %` 30 E < %= " 1 3 %` 4 E < %= " 2 3 %` 4 E < Converting (r, q) = (5, 30) gives (x, y) = (4. 3, 2. 5) and (x, y) = (3, 4) gives (r, q) = (5. 0, 53. 1). ³ Problem Two adjacent angles measure 12¡ 31¢ 45£ and 26¡ 54¢ 38£ respectively. -q$$"""< - 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. Then set the calculator to radian mode and calculate the sine of À / 6 radians. - %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. Example Degree mode Tan q<$$< - %B 3 45E< 25 Tan-1 %B 6 1E< 5 V %B 2 60 E < Cos Example Radian mode Tan q"<%B 3 g P 4 " E < %B 6 1E< r Tan-1 Cos 5 V %B 2 g P 4 "E< ³ Problem Find angle A of the right triangle below. 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 <. • ln yields the logarithm of a number ot the base of e (e ≈ 2. 718281828459). • e^ raises e to the power you specify.

Enter the operation (any combination of numbers, operations, or menu items and their arguments). [. . . ] For example: • For xÑy: x = 0 or (y < 0 and x is not an odd integer). • For tan: x = 90Ä, -90Ä, 270Ä, -270Ä, 450Ä, etc. , and equivalent for radian mode. • For }: Entering a simplify value of 0; using a simplify value of ‚ 1E10; attempting to simplify non-fractions. EQUATION LENGTH — An entry exceeds the digit limits (88 for entry line and 47 for stat entries or constant entries); for example, combining an entry with a constant that exceeds the limit. [. . . ]
