Work: Calculate the value of equation -90-arctan(0.1*0.1)-arctan(0.01*0.1)-arctan(0.1/0.375)-arctan(0.1/84.85)+arctan(0.1/3)+arctan(0.1/10.61) .
Question type: Mathematical calculation
Solution:
-90-arctan(0.1*0.1)-arctan(0.01*0.1)-arctan(0.1/0.375)-arctan(0.1/84.85)+arctan(0.1/3)+arctan(0.1/10.61)
=-90-arctan0.01-arctan(0.01*0.1)-arctan(0.1/0.375)-arctan(0.1/84.85)+arctan(0.1/3)+arctan(0.1/10.61)
=-90-arctan0.01-arctan0.001-arctan(0.1/0.375)-arctan(0.1/84.85)+arctan(0.1/3)+arctan(0.1/10.61)
=-90-arctan0.01-arctan0.001-arctan0.266667-arctan(0.1/84.85)+arctan(0.1/3)+arctan(0.1/10.61)
=-90-arctan0.01-arctan0.001-arctan0.266667-arctan0.001179+arctan(0.1/3)+arctan(0.1/10.61)
=-90-arctan0.01-arctan0.001-arctan0.266667-arctan0.001179+arctan0.033333+arctan(0.1/10.61)
=-90-arctan0.01-arctan0.001-arctan0.266667-arctan0.001179+arctan0.033333+arctan0.009425
=-90-0.01-arctan0.001-arctan0.266667-arctan0.001179+arctan0.033333+arctan0.009425
=-90-0.01-0.001-arctan0.266667-arctan0.001179+arctan0.033333+arctan0.009425
=-90-0.01-0.001-0.260603-arctan0.001179+arctan0.033333+arctan0.009425
=-90-0.01-0.001-0.260603-0.001179+arctan0.033333+arctan0.009425

=-90-0.01-0.001-0.260603-0.001179+0.033321+0.009425
=-90.01-0.001-0.260603-0.001179+0.033321+0.009425
=-90.011-0.260603-0.001179+0.033321+0.009425
=-90.271603-0.001179+0.033321+0.009425
=-90.272782+0.033321+0.009425
=-90.239461+0.009425
=-90.230036
Answer:-90-arctan(0.1*0.1)-arctan(0.01*0.1)-arctan(0.1/0.375)-arctan(0.1/84.85)+arctan(0.1/3)+arctan(0.1/10.61)=-90.230036
