Work: Calculate the value of equation 180-90-arctan(0.2*8)-arctan(0.5*8)+arctan(1.26*8)-arctan(0.012*8) .
Question type: Mathematical calculation
Solution:
180-90-arctan(0.2*8)-arctan(0.5*8)+arctan(1.26*8)-arctan(0.012*8)
=180-90-arctan1.6-arctan(0.5*8)+arctan(1.26*8)-arctan(0.012*8)
=180-90-arctan1.6-arctan4+arctan(1.26*8)-arctan(0.012*8)
=180-90-arctan1.6-arctan4+arctan10.08-arctan(0.012*8)
=180-90-arctan1.6-arctan4+arctan10.08-arctan0.096
=180-90-1.012197-arctan4+arctan10.08-arctan0.096
=180-90-1.012197-1.325818+arctan10.08-arctan0.096
=180-90-1.012197-1.325818+1.471914-arctan0.096
=180-90-1.012197-1.325818+1.471914-0.095707
=90-1.012197-1.325818+1.471914-0.095707
=88.987803-1.325818+1.471914-0.095707
=87.661985+1.471914-0.095707
=89.133899-0.095707
=89.038192
Answer:180-90-arctan(0.2*8)-arctan(0.5*8)+arctan(1.26*8)-arctan(0.012*8)=89.038192
