Trigonometric And Inverse Trigonometric Functions - Casio fx-9860G Series User Manual

k Trigonometric and Inverse Trigonometric Functions
• Be sure to set the angle unit before performing trigonometric function and inverse
trigonometric function calculations.
(90° = ––– radians = 100 grads) (90° = ––– radians = 100 grads)
• Be sure to specify Comp for Mode in the Setup screen.
