Work: Calculate the value of equation 90-arctan(0.12*13)-arctan(0.02*13)-arctan(0.04*13)-arctan(5.1*13)+arctan(0.77*13)+arctan(0.1476*13) .
Question type: Mathematical calculation
Solution:
90-arctan(0.12*13)-arctan(0.02*13)-arctan(0.04*13)-arctan(5.1*13)+arctan(0.77*13)+arctan(0.1476*13)
=90-arctan1.56-arctan(0.02*13)-arctan(0.04*13)-arctan(5.1*13)+arctan(0.77*13)+arctan(0.1476*13)
=90-arctan1.56-arctan0.26-arctan(0.04*13)-arctan(5.1*13)+arctan(0.77*13)+arctan(0.1476*13)
=90-arctan1.56-arctan0.26-arctan0.52-arctan(5.1*13)+arctan(0.77*13)+arctan(0.1476*13)
=90-arctan1.56-arctan0.26-arctan0.52-arctan66.3+arctan(0.77*13)+arctan(0.1476*13)
=90-arctan1.56-arctan0.26-arctan0.52-arctan66.3+arctan10.01+arctan(0.1476*13)
=90-arctan1.56-arctan0.26-arctan0.52-arctan66.3+arctan10.01+arctan1.9188
=90-1.000756-arctan0.26-arctan0.52-arctan66.3+arctan10.01+arctan1.9188
=90-1.000756-0.254368-arctan0.52-arctan66.3+arctan10.01+arctan1.9188
=90-1.000756-0.254368-0.479519-arctan66.3+arctan10.01+arctan1.9188
=90-1.000756-0.254368-0.479519-1.555715+arctan10.01+arctan1.9188
=90-1.000756-0.254368-0.479519-1.555715+1.471227+arctan1.9188
=90-1.000756-0.254368-0.479519-1.555715+1.471227+1.090365
=88.999244-0.254368-0.479519-1.555715+1.471227+1.090365
=88.744876-0.479519-1.555715+1.471227+1.090365
=88.265357-1.555715+1.471227+1.090365
=86.709642+1.471227+1.090365
=88.180869+1.090365
=89.271234
Answer:90-arctan(0.12*13)-arctan(0.02*13)-arctan(0.04*13)-arctan(5.1*13)+arctan(0.77*13)+arctan(0.1476*13)=89.271234
