For the sin , tan
will be provided in the following intervals:

A road sign indicates that there is a 5% slope. What is the angle measure-
ment in degrees and radians?
If the slope has an altitude of 5% it thus increases by 5m every 100m. The
sinus of the angle to find is 5 divided by 100, thus 0,05.

Initiates the input of Cartesian coordinates for
conversion into polar coordinates.
Initiates the input of polar coordinates for conversion
into Cartesian coordinates.
Used with [Pol(] or [SHIFT] [Rec(], it is placed between
x and y, or r and 0 to indicate the input of the 
coordinate.
Brackets ending the input of the pair of coordinates.
Displays the first coordinate after conversion, x or r.
Displays the second coordinate after conversion, y or 0 .
Initiates the input of Cartesian coordinates for
conversion into polar coordinates.
