Work: Calculate the value of equation 90-arctan(0.2*8)-arctan(0.5*8)-arctan(0.012*8)+arctan(1.26*8) .
Question type: Mathematical calculation
Solution:
90-arctan(0.2*8)-arctan(0.5*8)-arctan(0.012*8)+arctan(1.26*8)
=90-arctan1.6-arctan(0.5*8)-arctan(0.012*8)+arctan(1.26*8)
=90-arctan1.6-arctan4-arctan(0.012*8)+arctan(1.26*8)
=90-arctan1.6-arctan4-arctan0.096+arctan(1.26*8)
=90-arctan1.6-arctan4-arctan0.096+arctan10.08
=90-1.012197-arctan4-arctan0.096+arctan10.08
=90-1.012197-1.325818-arctan0.096+arctan10.08
=90-1.012197-1.325818-0.095707+arctan10.08
=90-1.012197-1.325818-0.095707+1.471914
=88.987803-1.325818-0.095707+1.471914
=87.661985-0.095707+1.471914
=87.566278+1.471914
=89.038192
Answer:90-arctan(0.2*8)-arctan(0.5*8)-arctan(0.012*8)+arctan(1.26*8)=89.038192
