Work: Calculate the value of equation 180-90-arctan(8/2)-arctan(8/5)+arctan(1.05*8)-arctan(0.014*8) .
Question type: Mathematical calculation
Solution:
180-90-arctan(8/2)-arctan(8/5)+arctan(1.05*8)-arctan(0.014*8)
=180-90-arctan4-arctan(8/5)+arctan(1.05*8)-arctan(0.014*8)
=180-90-arctan4-arctan1.6+arctan(1.05*8)-arctan(0.014*8)
=180-90-arctan4-arctan1.6+arctan8.4-arctan(0.014*8)
=180-90-arctan4-arctan1.6+arctan8.4-arctan0.112
=180-90-1.325818-arctan1.6+arctan8.4-arctan0.112
=180-90-1.325818-1.012197+arctan8.4-arctan0.112
=180-90-1.325818-1.012197+1.452306-arctan0.112
=180-90-1.325818-1.012197+1.452306-0.111535
=90-1.325818-1.012197+1.452306-0.111535
=88.674182-1.012197+1.452306-0.111535
=87.661985+1.452306-0.111535
=89.114291-0.111535
=89.002756
Answer:180-90-arctan(8/2)-arctan(8/5)+arctan(1.05*8)-arctan(0.014*8)=89.002756
