Arithmetic functions

Note: If a function takes more than one argument, the arguments are separated with semicolon ';'.

Inverse trigonometric functions

Note: On the display tab you can select between degrees, radians and gradians. In these samples we assume that the 'rad' option is selected. This affects the output (result) value.

asin(x)

Inverse sine (arc sine) of x
e.g. asin(0.7)=0.775...

acos(x)

Inverse cosine (arc cosine) of x
acos(0.9)=0.451...

atan(x) or atg(x)

Inverse tangent (arc tangent) of x
atan(3.3)=1.276...

acot(x) or actg(x)

Inverse cotangent (arc cotangent) of x
acot(10)=0.099...
