# Calculates in Radians even tough I set it to Degree

The trigonometric calculations are in radians. It is by default set to Degrees, but still calculates in Radians. Switching it out and then back does not fix it either. 1

The problem occured on Scientific Calculator site ( https://www.geogebra.org/sc... ) 1

Which calculation ? Please, give an example (or a screenshot) 1

The calculation was: sin(9 / 7)

the result always stayed in radians, regardless of what angle unit I chose in the settings menu. 1

yes

It is the same in all GeoGebra apps

set to degrees :

sin(30°) is 0.5

but sin(60/2) or sin(2*15) is -0.98...

you have to write sin(60°/2) or sin(2*15°)

So, even you set degrees, you have to write "°"

(perhaps you have noticed that when you write sin(30) GeoGebra add the ° : so it is sin(30°) and the result is 0.5)

It doesn't work as a calculator (CASIO, TI,...), but it works as mathematics !

sin(30°) = 0.5 and sin(30) = -0.98
