Work: Calculate the value of equation arctan(60/2)+arctan(60/6)-arctan(60/12)-arctan(60/60)-arctan(60/80) .
Question type: Mathematical calculation
Solution:
arctan(60/2)+arctan(60/6)-arctan(60/12)-arctan(60/60)-arctan(60/80)
=arctan30+arctan(60/6)-arctan(60/12)-arctan(60/60)-arctan(60/80)
=arctan30+arctan10-arctan(60/12)-arctan(60/60)-arctan(60/80)
=arctan30+arctan10-arctan5-arctan(60/60)-arctan(60/80)
=arctan30+arctan10-arctan5-arctan1-arctan(60/80)
=arctan30+arctan10-arctan5-arctan1-arctan0.75
=1.537475+arctan10-arctan5-arctan1-arctan0.75
=1.537475+1.471128-arctan5-arctan1-arctan0.75
=1.537475+1.471128-1.373401-arctan1-arctan0.75
=1.537475+1.471128-1.373401-0.785398-arctan0.75
=1.537475+1.471128-1.373401-0.785398-0.643501
=3.008603-1.373401-0.785398-0.643501
=1.635202-0.785398-0.643501
=0.849804-0.643501
=0.206303
Answer:arctan(60/2)+arctan(60/6)-arctan(60/12)-arctan(60/60)-arctan(60/80)=0.206303
