In mathematics, the inverse trigonometric functions are the inverse functions of the trigonometric functions.
For example, arcsin(0.1) = 5.73917, arcsin(0.1) = 0.10017 radians, arcsin(0.1) = 0.03188 π radians
arccos(0.1) = 84.26083, arccos(0.1) = 1.47063 radians, arccos(0.1) = 0.46812 π radians
arctan(0.1) = 5.71059, arctan(0.1) = 0.09967 radians, arctan(0.1) = 0.03173 π radians
arccot(0.1) = 84.28941, arccot(0.1) = 1.47113 radians, arccot(0.1) = 0.46827 π radians
arcsec(5) = 78.46304, arcsec(5) = 1.36944 radians, arcsec(5) = 0.43591 π radians
arccsc(5) = 11.53696, arccsc(5) = 0.20136 radians, arccsc(5) = 0.06409 π radians
