WebVal = COS(30*PI/180) ‘The variable value is now equal to 0.86602. So, in the above formula, angle 30 is converted into radians first and then COS. Things to Remember. If the angle is given in degrees for which we have to calculate COS, we have to calculate RADIANS for the same, or we can multiply the angle by PI()/180. WebBy default all of the trigonometric functions take radians as parameters but we can convert radians to degrees and vice versa as well in NumPy. Note: radians values are pi/180 * degree_values. Example Get your own Python Server. Convert all of the values in following array arr to radians: import numpy as np. arr = np.array ( [90, 180, 270, 360])
