    解:
          -90-arctan(0.1*0.01)-arctan(0.01*0.01)-arctan(0.01/0.375)-arctan(0.01/84.85)+arctan(0.01/3)+arctan(0.01/10.61)
        =-90-arctan0.001-arctan(0.01*0.01)-arctan(0.01/0.375)-arctan(0.01/84.85)+arctan(0.01/3)+arctan(0.01/10.61)
        =-90-arctan0.001-arctan0.0001-arctan(0.01/0.375)-arctan(0.01/84.85)+arctan(0.01/3)+arctan(0.01/10.61)
        =-90-arctan0.001-arctan0.0001-arctan0.026667-arctan(0.01/84.85)+arctan(0.01/3)+arctan(0.01/10.61)
        =-90-arctan0.001-arctan0.0001-arctan0.026667-arctan0.000118+arctan(0.01/3)+arctan(0.01/10.61)
        =-90-arctan0.001-arctan0.0001-arctan0.026667-arctan0.000118+arctan0.003333+arctan(0.01/10.61)
        =-90-arctan0.001-arctan0.0001-arctan0.026667-arctan0.000118+arctan0.003333+arctan0.000943
        =-90-0.001-arctan0.0001-arctan0.026667-arctan0.000118+arctan0.003333+arctan0.000943
        =-90-0.001-0.0001-arctan0.026667-arctan0.000118+arctan0.003333+arctan0.000943
        =-90-0.001-0.0001-0.026661-arctan0.000118+arctan0.003333+arctan0.000943
        =-90-0.001-0.0001-0.026661-0.000118+arctan0.003333+arctan0.000943
        =-90-0.001-0.0001-0.026661-0.000118+0.003333+arctan0.000943
        =-90-0.001-0.0001-0.026661-0.000118+0.003333+0.000943
        =-90.001-0.0001-0.026661-0.000118+0.003333+0.000943

        =-90.027761-0.000118+0.003333+0.000943
        =-90.027879+0.003333+0.000943
        =-90.024546+0.000943
        =-90.023603
    答案:-90-arctan(0.1*0.01)-arctan(0.01*0.01)-arctan(0.01/0.375)-arctan(0.01/84.85)+arctan(0.01/3)+arctan(0.01/10.61)=-90.023603
