Work: Calculate the value of equation 90-arctan(0.1*8.19)-arctan(0.2*8.19)-arctan(0.0546*8.19)-arctan(6.25*8.19)+arctan(1.25*8.19)+arctan(0.273*8.19) .
Question type: Mathematical calculation
Solution:
90-arctan(0.1*8.19)-arctan(0.2*8.19)-arctan(0.0546*8.19)-arctan(6.25*8.19)+arctan(1.25*8.19)+arctan(0.273*8.19)
=90-arctan0.819-arctan(0.2*8.19)-arctan(0.0546*8.19)-arctan(6.25*8.19)+arctan(1.25*8.19)+arctan(0.273*8.19)
=90-arctan0.819-arctan1.638-arctan(0.0546*8.19)-arctan(6.25*8.19)+arctan(1.25*8.19)+arctan(0.273*8.19)
=90-arctan0.819-arctan1.638-arctan0.447174-arctan(6.25*8.19)+arctan(1.25*8.19)+arctan(0.273*8.19)
=90-arctan0.819-arctan1.638-arctan0.447174-arctan51.1875+arctan(1.25*8.19)+arctan(0.273*8.19)
=90-arctan0.819-arctan1.638-arctan0.447174-arctan51.1875+arctan10.2375+arctan(0.273*8.19)
=90-arctan0.819-arctan1.638-arctan0.447174-arctan51.1875+arctan10.2375+arctan2.23587
=90-0.686219-arctan1.638-arctan0.447174-arctan51.1875+arctan10.2375+arctan2.23587
=90-0.686219-1.022692-arctan0.447174-arctan51.1875+arctan10.2375+arctan2.23587
=90-0.686219-1.022692-0.420501-arctan51.1875+arctan10.2375+arctan2.23587
=90-0.686219-1.022692-0.420501-1.551263+arctan10.2375+arctan2.23587
=90-0.686219-1.022692-0.420501-1.551263+1.473425+arctan2.23587
=90-0.686219-1.022692-0.420501-1.551263+1.473425+1.150229
=89.313781-1.022692-0.420501-1.551263+1.473425+1.150229
=88.291089-0.420501-1.551263+1.473425+1.150229
=87.870588-1.551263+1.473425+1.150229
=86.319325+1.473425+1.150229
=87.79275+1.150229
=88.942979
Answer:90-arctan(0.1*8.19)-arctan(0.2*8.19)-arctan(0.0546*8.19)-arctan(6.25*8.19)+arctan(1.25*8.19)+arctan(0.273*8.19)=88.942979
