Work: Calculate the value of equation -90-2*arctan(314.320444/25)-arctan(314.320444)+arctan(314.320444/2) .
Question type: Mathematical calculation
Solution:
-90-2*arctan(314.320444/25)-arctan(314.320444)+arctan(314.320444/2)
=-90-2*arctan12.572818-arctan(314.320444)+arctan(314.320444/2)
=-90-2*arctan12.572818-arctan314.320444+arctan(314.320444/2)
=-90-2*arctan12.572818-arctan314.320444+arctan157.160222
=-90-2*1.491427-arctan314.320444+arctan157.160222
=-90-2*1.491427-1.567615+arctan157.160222
=-90-2*1.491427-1.567615+1.564433
=-90-2.982854-1.567615+1.564433
=-92.982854-1.567615+1.564433
=-94.550469+1.564433
=-92.986036
Answer:-90-2*arctan(314.320444/25)-arctan(314.320444)+arctan(314.320444/2)=-92.986036
