I want know what usage for atan2(x) function in Geogebra.
thanks alot for your help
try: tan^-1(2) x
I know definition of this function but don't know how this can help in geogebra. Can you send file for me for application of this function in geogebra file.
if (x,y) is in second quadrant (ie) then 90º<=atan2(y,x) <=180º so atan2 is more useful for position of a point
Please send for me ggb file for this if used in working.
