Work: Calculate the value of equation -90-arctan(0.1*150)-arctan(0.01*150)-arctan(150/0.375)-arctan(150/84.85)+arctan(150/3)+arctan(150/10.61) .
Question type: Mathematical calculation
Solution:
-90-arctan(0.1*150)-arctan(0.01*150)-arctan(150/0.375)-arctan(150/84.85)+arctan(150/3)+arctan(150/10.61)
=-90-arctan15-arctan(0.01*150)-arctan(150/0.375)-arctan(150/84.85)+arctan(150/3)+arctan(150/10.61)
=-90-arctan15-arctan1.5-arctan(150/0.375)-arctan(150/84.85)+arctan(150/3)+arctan(150/10.61)
=-90-arctan15-arctan1.5-arctan400-arctan(150/84.85)+arctan(150/3)+arctan(150/10.61)
=-90-arctan15-arctan1.5-arctan400-arctan1.767826+arctan(150/3)+arctan(150/10.61)
=-90-arctan15-arctan1.5-arctan400-arctan1.767826+arctan50+arctan(150/10.61)
=-90-arctan15-arctan1.5-arctan400-arctan1.767826+arctan50+arctan14.137606
=-90-1.504228-arctan1.5-arctan400-arctan1.767826+arctan50+arctan14.137606
=-90-1.504228-0.982794-arctan400-arctan1.767826+arctan50+arctan14.137606
=-90-1.504228-0.982794-1.568296-arctan1.767826+arctan50+arctan14.137606
=-90-1.504228-0.982794-1.568296-1.056005+arctan50+arctan14.137606
=-90-1.504228-0.982794-1.568296-1.056005+1.550799+arctan14.137606
=-90-1.504228-0.982794-1.568296-1.056005+1.550799+1.500181
=-91.504228-0.982794-1.568296-1.056005+1.550799+1.500181
=-92.487022-1.568296-1.056005+1.550799+1.500181
=-94.055318-1.056005+1.550799+1.500181
=-95.111323+1.550799+1.500181
=-93.560524+1.500181
=-92.060343
Answer:-90-arctan(0.1*150)-arctan(0.01*150)-arctan(150/0.375)-arctan(150/84.85)+arctan(150/3)+arctan(150/10.61)=-92.060343
