Converting an Input Value to the
Calculator’s Default Angle Unit
After inputting a value, press
(Angle Unit)* to display the angle unit
specification menu shown below. Press the number key that corresponds
to the angle unit of the input value. The calculator will automatically
convert it to the calculator’s default angle unit.
* Depending on the calculation mode, you should press
.
° : Degrees,
r
: Radians,
g
: Gradians
Example 1: To convert the following values to degrees:
π
2
radians = 90°,
50 grads = 45°
The following procedure assumes that the calculator’s default angle unit
is degrees.
(π) 2
(Angle Unit) (
r
)
50 (Angle Unit) (
g
)
Example 2: cos(π radians) = -1, cos(100 grads) = 0
(π)
(Angle Unit) (
r
)
100 (Angle Unit) (
g
)
