When looking for the 2-pi range version of np.atan (which turns out to be np.atan2) I found that there's a np.arctan as well - is there some difference between np.arctan and np.atan? The test below doesn't seem to show any difference between atan and arctan , or between atan2 and arctan2: import numpy as np for i in np.arange(0,2*np.pi,.1): x = np.cos(i) y = np.sin(i) th = np.atan(y/x) th2 = np.atan2(y,x) th3 = np.arctan(y/x) th4 = np.arctan2(y,x) print(f'atan {th} atan2 {th2} arctan {th3} arctan2 {th4}') Continue reading...
