Trigonometric Functions
To change the default angle unit (degrees, radians, grads), press the key a number of times until you reach the angle unit setup screen shown below.
Press the number key (, , or ) that corresponds to the angle unit you want to use.
(90° = π/2 radians = 100 grads)
Example 1: sin 30° = 0.5 (Angle unit: Deg)
-
・・・・・(Deg)
30 - 0.5
Example 2: cos(π3) = 0.5 (Angle unit: Rad)
-
・・・・・(Rad)
(π)3 - 0.5
Example 3: tan(-35) = -0.612800788 (Angle unit: Gra)
-
・・・・・(Gra)
35 - -0.612800788
