Work: Calculate the value of equation 90-arctan(0.2*8)-arctan(0.5*8)+arctan(0.64*8)-arctan(0.025*8) .
Question type: Mathematical calculation
Solution:
90-arctan(0.2*8)-arctan(0.5*8)+arctan(0.64*8)-arctan(0.025*8)
=90-arctan1.6-arctan(0.5*8)+arctan(0.64*8)-arctan(0.025*8)
=90-arctan1.6-arctan4+arctan(0.64*8)-arctan(0.025*8)
=90-arctan1.6-arctan4+arctan5.12-arctan(0.025*8)
=90-arctan1.6-arctan4+arctan5.12-arctan0.2
=90-1.012197-arctan4+arctan5.12-arctan0.2
=90-1.012197-1.325818+arctan5.12-arctan0.2
=90-1.012197-1.325818+1.377912-arctan0.2
=90-1.012197-1.325818+1.377912-0.197396
=88.987803-1.325818+1.377912-0.197396
=87.661985+1.377912-0.197396
=89.039897-0.197396
=88.842501
Answer:90-arctan(0.2*8)-arctan(0.5*8)+arctan(0.64*8)-arctan(0.025*8)=88.842501
