Work: Calculate the value of equation 180-90-arctan(0.623)-arctan(0.2*0.623)-arctan(102.89*0.623)+arctan(16.05*0.623) .
Question type: Mathematical calculation
Solution:
180-90-arctan(0.623)-arctan(0.2*0.623)-arctan(102.89*0.623)+arctan(16.05*0.623)
=180-90-arctan0.623-arctan(0.2*0.623)-arctan(102.89*0.623)+arctan(16.05*0.623)
=180-90-arctan0.623-arctan0.1246-arctan(102.89*0.623)+arctan(16.05*0.623)
=180-90-arctan0.623-arctan0.1246-arctan64.10047+arctan(16.05*0.623)
=180-90-arctan0.623-arctan0.1246-arctan64.10047+arctan9.99915
=180-90-0.55716-arctan0.1246-arctan64.10047+arctan9.99915
=180-90-0.55716-0.123961-arctan64.10047+arctan9.99915
=180-90-0.55716-0.123961-1.555197+arctan9.99915
=180-90-0.55716-0.123961-1.555197+1.471119
=90-0.55716-0.123961-1.555197+1.471119
=89.44284-0.123961-1.555197+1.471119
=89.318879-1.555197+1.471119
=87.763682+1.471119
=89.234801
Answer:180-90-arctan(0.623)-arctan(0.2*0.623)-arctan(102.89*0.623)+arctan(16.05*0.623)=89.234801
