Work: Calculate the value of equation -90-arctan(0.1*8)-arctan(0.01*8)-arctan(8/0.375)-arctan(8/84.85)+arctan(8/3)+arctan(8/10.61) .
Question type: Mathematical calculation
Solution:
-90-arctan(0.1*8)-arctan(0.01*8)-arctan(8/0.375)-arctan(8/84.85)+arctan(8/3)+arctan(8/10.61)
=-90-arctan0.8-arctan(0.01*8)-arctan(8/0.375)-arctan(8/84.85)+arctan(8/3)+arctan(8/10.61)
=-90-arctan0.8-arctan0.08-arctan(8/0.375)-arctan(8/84.85)+arctan(8/3)+arctan(8/10.61)
=-90-arctan0.8-arctan0.08-arctan21.333333-arctan(8/84.85)+arctan(8/3)+arctan(8/10.61)
=-90-arctan0.8-arctan0.08-arctan21.333333-arctan0.094284+arctan(8/3)+arctan(8/10.61)
=-90-arctan0.8-arctan0.08-arctan21.333333-arctan0.094284+arctan2.666667+arctan(8/10.61)
=-90-arctan0.8-arctan0.08-arctan21.333333-arctan0.094284+arctan2.666667+arctan0.754006
=-90-0.674741-arctan0.08-arctan21.333333-arctan0.094284+arctan2.666667+arctan0.754006
=-90-0.674741-0.07983-arctan21.333333-arctan0.094284+arctan2.666667+arctan0.754006
=-90-0.674741-0.07983-1.523956-arctan0.094284+arctan2.666667+arctan0.754006
=-90-0.674741-0.07983-1.523956-0.094006+arctan2.666667+arctan0.754006
=-90-0.674741-0.07983-1.523956-0.094006+1.212026+arctan0.754006
=-90-0.674741-0.07983-1.523956-0.094006+1.212026+0.64606
=-90.674741-0.07983-1.523956-0.094006+1.212026+0.64606
=-90.754571-1.523956-0.094006+1.212026+0.64606
=-92.278527-0.094006+1.212026+0.64606
=-92.372533+1.212026+0.64606
=-91.160507+0.64606
=-90.514447
Answer:-90-arctan(0.1*8)-arctan(0.01*8)-arctan(8/0.375)-arctan(8/84.85)+arctan(8/3)+arctan(8/10.61)=-90.514447
