Work: Calculate the value of equation -90-arctan(0.1*4)-arctan(0.01*4)-arctan(4/0.375)-arctan(4/84.85)+arctan(4/3)+arctan(4/10.61) .
Question type: Mathematical calculation
Solution:
-90-arctan(0.1*4)-arctan(0.01*4)-arctan(4/0.375)-arctan(4/84.85)+arctan(4/3)+arctan(4/10.61)
=-90-arctan0.4-arctan(0.01*4)-arctan(4/0.375)-arctan(4/84.85)+arctan(4/3)+arctan(4/10.61)
=-90-arctan0.4-arctan0.04-arctan(4/0.375)-arctan(4/84.85)+arctan(4/3)+arctan(4/10.61)
=-90-arctan0.4-arctan0.04-arctan10.666667-arctan(4/84.85)+arctan(4/3)+arctan(4/10.61)
=-90-arctan0.4-arctan0.04-arctan10.666667-arctan0.047142+arctan(4/3)+arctan(4/10.61)
=-90-arctan0.4-arctan0.04-arctan10.666667-arctan0.047142+arctan1.333333+arctan(4/10.61)
=-90-arctan0.4-arctan0.04-arctan10.666667-arctan0.047142+arctan1.333333+arctan0.377003

=-90-0.380506-0.039979-1.47732-0.047107+0.927295+arctan0.377003
=-90-0.380506-0.039979-1.47732-0.047107+0.927295+0.360526
=-90.380506-0.039979-1.47732-0.047107+0.927295+0.360526
=-90.420485-1.47732-0.047107+0.927295+0.360526
=-91.897805-0.047107+0.927295+0.360526
=-91.944912+0.927295+0.360526
=-91.017617+0.360526
=-90.657091
Answer:-90-arctan(0.1*4)-arctan(0.01*4)-arctan(4/0.375)-arctan(4/84.85)+arctan(4/3)+arctan(4/10.61)=-90.657091
