The CalcES Scientific Calculator supports 3 angle units:
If the Sin(90)
on your calculator is not evaluating to 1
, please ensure that your calculator angle unit is set to
degrees, not radians.
Sin(90) = 0.894
in Radian modeSin(90) = 1
in Degree modeSin(90) = 0.988
in Gradian modeFollow these steps to change angle unit:
Sin(60) = Sqrt(3)/2 ~ 0.866
Sin(Pi/4) = Sqrt(2)/2 ~ 0.7
These angle units can be converted into one another using conversion formulas:
