Work: Calculate the value of equation -π+arctan(2/2)+arctan(2/6)-arctan(2/12)-arctan(2/60)-arctan(2/80) .
Question type: Mathematical calculation
Solution:
-π+arctan(2/2)+arctan(2/6)-arctan(2/12)-arctan(2/60)-arctan(2/80)
=-π+arctan1+arctan(2/6)-arctan(2/12)-arctan(2/60)-arctan(2/80)
=-π+arctan1+arctan0.333333-arctan(2/12)-arctan(2/60)-arctan(2/80)
=-π+arctan1+arctan0.333333-arctan0.166667-arctan(2/60)-arctan(2/80)
=-π+arctan1+arctan0.333333-arctan0.166667-arctan0.033333-arctan(2/80)
=-π+arctan1+arctan0.333333-arctan0.166667-arctan0.033333-arctan0.025
=-π+0.785398+arctan0.333333-arctan0.166667-arctan0.033333-arctan0.025
=-π+0.785398+0.32175-arctan0.166667-arctan0.033333-arctan0.025
=-π+0.785398+0.32175-0.165149-arctan0.033333-arctan0.025
=-π+0.785398+0.32175-0.165149-0.033321-arctan0.025
=-π+0.785398+0.32175-0.165149-0.033321-0.024995
=0.785398+0.32175-0.165149-0.033321-0.024995
=1.107148-0.165149-0.033321-0.024995
=0.941999-0.033321-0.024995
=0.908678-0.024995
=0.883683
Answer:-π+arctan(2/2)+arctan(2/6)-arctan(2/12)-arctan(2/60)-arctan(2/80)=0.883683
