Work: Calculate the value of equation 90-arctan(1.44/2)-arctan(1.44/10)-arctan(239.46*1.44)+arctan(6.94*1.44) .
Question type: Mathematical calculation
Solution:
90-arctan(1.44/2)-arctan(1.44/10)-arctan(239.46*1.44)+arctan(6.94*1.44)
=90-arctan0.72-arctan(1.44/10)-arctan(239.46*1.44)+arctan(6.94*1.44)
=90-arctan0.72-arctan0.144-arctan(239.46*1.44)+arctan(6.94*1.44)
=90-arctan0.72-arctan0.144-arctan344.8224+arctan(6.94*1.44)
=90-arctan0.72-arctan0.144-arctan344.8224+arctan9.9936
=90-0.624023-arctan0.144-arctan344.8224+arctan9.9936
=90-0.624023-0.143017-arctan344.8224+arctan9.9936
=90-0.624023-0.143017-1.567896+arctan9.9936
=90-0.624023-0.143017-1.567896+1.471064
=89.375977-0.143017-1.567896+1.471064
=89.23296-1.567896+1.471064
=87.665064+1.471064
=89.136128
Answer:90-arctan(1.44/2)-arctan(1.44/10)-arctan(239.46*1.44)+arctan(6.94*1.44)=89.136128
