Work: Calculate the value of equation 90+arctan(10)-arctan(0.1*10)-arctan(0.02*10)-arctan(0.01*10)-arctan(10*10) .
Question type: Mathematical calculation
Solution:
90+arctan(10)-arctan(0.1*10)-arctan(0.02*10)-arctan(0.01*10)-arctan(10*10)
=90+arctan10-arctan(0.1*10)-arctan(0.02*10)-arctan(0.01*10)-arctan(10*10)
=90+arctan10-arctan1-arctan(0.02*10)-arctan(0.01*10)-arctan(10*10)
=90+arctan10-arctan1-arctan0.2-arctan(0.01*10)-arctan(10*10)
=90+arctan10-arctan1-arctan0.2-arctan0.1-arctan(10*10)
=90+arctan10-arctan1-arctan0.2-arctan0.1-arctan100
=90+1.471128-arctan1-arctan0.2-arctan0.1-arctan100
=90+1.471128-0.785398-arctan0.2-arctan0.1-arctan100
=90+1.471128-0.785398-0.197396-arctan0.1-arctan100
=90+1.471128-0.785398-0.197396-0.099669-arctan100
=90+1.471128-0.785398-0.197396-0.099669-1.560797
=91.471128-0.785398-0.197396-0.099669-1.560797
=90.68573-0.197396-0.099669-1.560797
=90.488334-0.099669-1.560797
=90.388665-1.560797
=88.827868
Answer:90+arctan(10)-arctan(0.1*10)-arctan(0.02*10)-arctan(0.01*10)-arctan(10*10)=88.827868
