解:
90-arctan(0.1*8.19)-arctan(0.2*8.19)-arctan(0.0546*8.19)-arctan(6.25*8.19)+arctan(1.25*8.19)+arctan(0.273*8.19)
=90-arctan0.819-arctan(0.2*8.19)-arctan(0.0546*8.19)-arctan(6.25*8.19)+arctan(1.25*8.19)+arctan(0.273*8.19)
=90-arctan0.819-arctan1.638-arctan(0.0546*8.19)-arctan(6.25*8.19)+arctan(1.25*8.19)+arctan(0.273*8.19)
