Work: Calculate the value of equation arctan(12/2)+arctan(12/6)-arctan(12/12)-arctan(12/60)-arctan(12/80) .
Question type: Mathematical calculation
Solution:
arctan(12/2)+arctan(12/6)-arctan(12/12)-arctan(12/60)-arctan(12/80)
=arctan6+arctan(12/6)-arctan(12/12)-arctan(12/60)-arctan(12/80)
=arctan6+arctan2-arctan(12/12)-arctan(12/60)-arctan(12/80)
=arctan6+arctan2-arctan1-arctan(12/60)-arctan(12/80)
=arctan6+arctan2-arctan1-arctan0.2-arctan(12/80)
=arctan6+arctan2-arctan1-arctan0.2-arctan0.15
=1.405648+arctan2-arctan1-arctan0.2-arctan0.15
=1.405648+1.107149-arctan1-arctan0.2-arctan0.15
=1.405648+1.107149-0.785398-arctan0.2-arctan0.15
=1.405648+1.107149-0.785398-0.197396-arctan0.15
=1.405648+1.107149-0.785398-0.197396-0.14889
=2.512797-0.785398-0.197396-0.14889
=1.727399-0.197396-0.14889
=1.530003-0.14889
=1.381113
Answer:arctan(12/2)+arctan(12/6)-arctan(12/12)-arctan(12/60)-arctan(12/80)=1.381113
