Work: Calculate the value of equation arctan(0.77*21)+90-arctan(0.1*21)-arctan(0.01*21)-arctan(0.02*21)-arctan(21*9.1)+arctan(21*0.1241)-arctan(21*0.0183) .
Question type: Mathematical calculation
Solution:
arctan(0.77*21)+90-arctan(0.1*21)-arctan(0.01*21)-arctan(0.02*21)-arctan(21*9.1)+arctan(21*0.1241)-arctan(21*0.0183)
=arctan16.17+90-arctan(0.1*21)-arctan(0.01*21)-arctan(0.02*21)-arctan(21*9.1)+arctan(21*0.1241)-arctan(21*0.0183)
=arctan16.17+90-arctan2.1-arctan(0.01*21)-arctan(0.02*21)-arctan(21*9.1)+arctan(21*0.1241)-arctan(21*0.0183)
