Work: Calculate the value of equation 90+arctan(0.23×4.6)-arctan(0.5×4.6)-arctan(0.46)-arctan(0.023×4.6) .
Question type: Mathematical calculation
Solution:
90+arctan(0.23×4.6)-arctan(0.5×4.6)-arctan(0.46)-arctan(0.023×4.6)
=90+arctan1.058-arctan(0.5×4.6)-arctan(0.46)-arctan(0.023×4.6)
=90+arctan1.058-arctan2.3-arctan(0.46)-arctan(0.023×4.6)
=90+arctan1.058-arctan2.3-arctan0.46-arctan(0.023×4.6)
=90+arctan1.058-arctan2.3-arctan0.46-arctan0.1058
=90+0.813573-arctan2.3-arctan0.46-arctan0.1058
=90+0.813573-1.160669-arctan0.46-arctan0.1058
=90+0.813573-1.160669-0.431139-arctan0.1058
=90+0.813573-1.160669-0.431139-0.105408
=90.813573-1.160669-0.431139-0.105408
=89.652904-0.431139-0.105408
=89.221765-0.105408
=89.116357
Answer:90+arctan(0.23×4.6)-arctan(0.5×4.6)-arctan(0.46)-arctan(0.023×4.6)=89.116357
