Trigonometric and inverse trigonometric functions
When using those keys, make sure the calculator is set for the angular unit you want.
Note: Before using a DMS value in a calculation, you must convert it to decimal with
[DRG].
Example
cos (p/3 rad) = 0.5
tan (–35 grad) =
–0.612800788
2sin 45º × cos 65º =
0.597672477
sin 0.5 = 30

cos (√2/2) = 0.785398163

rad = p/4 rad
tan 0.741 = 36.53844577º
–1
= 36º32'18.4"
Division with Quotient and Remainder
You can use [2nd] [÷R] to get the quotient and remainder of division operations.
Note: If one of the following conditions are present when performing an operation
with calculation and display of remainder, the calculation will be treated as a normal
division (without calculation or display of remainder).
a) When the dividend or the divisor is a great value.
b) When the dividend or the divisor is a negative value.
c) When the quotient is > 99.
Example
33 ÷ R 6
Hyperbolic and inverse hyperbolic functions
To access hyperbolic functions, press [HYP] and then the function.
Note: DEG, RAD, or GRAD does not affect hyperbolic calculations.
