Work: Calculate the value of equation 90+arctan(10/3)+arctan(30/20)-arctan(10)-arctan(5)-arctan(2/3) .
Question type: Mathematical calculation
Solution:
90+arctan(10/3)+arctan(30/20)-arctan(10)-arctan(5)-arctan(2/3)
=90+arctan3.333333+arctan(30/20)-arctan(10)-arctan(5)-arctan(2/3)
=90+arctan3.333333+arctan1.5-arctan(10)-arctan(5)-arctan(2/3)
=90+arctan3.333333+arctan1.5-arctan10-arctan(5)-arctan(2/3)
=90+arctan3.333333+arctan1.5-arctan10-arctan5-arctan(2/3)
=90+arctan3.333333+arctan1.5-arctan10-arctan5-arctan0.666667
=90+1.27934+arctan1.5-arctan10-arctan5-arctan0.666667
=90+1.27934+0.982794-arctan10-arctan5-arctan0.666667
=90+1.27934+0.982794-1.471128-arctan5-arctan0.666667
=90+1.27934+0.982794-1.471128-1.373401-arctan0.666667
=90+1.27934+0.982794-1.471128-1.373401-0.588003
=91.27934+0.982794-1.471128-1.373401-0.588003
=92.262134-1.471128-1.373401-0.588003
=90.791006-1.373401-0.588003
=89.417605-0.588003
=88.829602
Answer:90+arctan(10/3)+arctan(30/20)-arctan(10)-arctan(5)-arctan(2/3)=88.829602
