% =
% = displays the choice of two submenus that enable you to specify the angle unit modifier as degrees (°), minutes ('), seconds ("), radian (r), or convert units using 4DMS. You can also convert between rectangular coordinate form (R) and polar coordinate form (P).
Choose an angle mode from the mode screen. You can choose from
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.

Convert polar coordinates (r,q)=(5,30) into rectangular coordinates. Then convert rectangular coordinates (x,y) = (3,4) into polar coordinates. Round the results to one decimal place.

% = " 1 3 % ` 4 E < % = " 2 3 % ` 4 E < |
|
Converting (r,q) = (5,30) gives (x,y) = (4.3,2.5) and converting
(x,y) = (3,4) gives (r,q) = (5.0,53.1).
³ Problem
Two adjacent angles measure 12Ä 31Å 45Æ and 26Ä 54Å 38 Æ respectively. Add the two angles and display the result in DMS format. Round the results to two decimal places.

The result is 39 degrees, 26 minutes and 23 seconds.
³ Problem
It is known that 30Ä = À / 6 radians. In the default mode, degrees, find the sine of 30Ä. Then set the calculator to radian mode and calculate the sine of À / 6 radians.
