cos, sin and tan reverses fucntion

[Michel]

Hi,

How it is possible to obtain a reverse function for
cosinus, sinus or tangente like
COS(30) = 0,866025...
and COS-1(0,866025...) = 30

Regards, Michel

The reverse functions for COS, SIN and TAN are ACOS, ASIN and ATAN.
Note that angles in these functions are expressed in radians, not degrees.
You can convert between radians and degrees using the functions RADIANS and
DEGREES.
