Work: Calculate the value of equation 90+arctan(0.09*20.1)-arctan(0.2*20.1)-arctan(0.0144*20.1)-arctan(0.0625*20.1) .
Question type: Mathematical calculation
Solution:
90+arctan(0.09*20.1)-arctan(0.2*20.1)-arctan(0.0144*20.1)-arctan(0.0625*20.1)
=90+arctan1.809-arctan(0.2*20.1)-arctan(0.0144*20.1)-arctan(0.0625*20.1)
=90+arctan1.809-arctan4.02-arctan(0.0144*20.1)-arctan(0.0625*20.1)
=90+arctan1.809-arctan4.02-arctan0.28944-arctan(0.0625*20.1)
=90+arctan1.809-arctan4.02-arctan0.28944-arctan1.25625
=90+1.065812-arctan4.02-arctan0.28944-arctan1.25625
=90+1.065812-1.326989-arctan0.28944-arctan1.25625
=90+1.065812-1.326989-0.281741-arctan1.25625
=90+1.065812-1.326989-0.281741-0.898487
=91.065812-1.326989-0.281741-0.898487
=89.738823-0.281741-0.898487
=89.457082-0.898487
=88.558595
Answer:90+arctan(0.09*20.1)-arctan(0.2*20.1)-arctan(0.0144*20.1)-arctan(0.0625*20.1)=88.558595
