Work: Calculate the value of equation -90-arctan(0.1*50)-arctan(0.01*50)-arctan(50/0.375)-arctan(50/84.85)+arctan(50/3)+arctan(50/10.61) .
Question type: Mathematical calculation
Solution:
-90-arctan(0.1*50)-arctan(0.01*50)-arctan(50/0.375)-arctan(50/84.85)+arctan(50/3)+arctan(50/10.61)
=-90-arctan5-arctan(0.01*50)-arctan(50/0.375)-arctan(50/84.85)+arctan(50/3)+arctan(50/10.61)
=-90-arctan5-arctan0.5-arctan(50/0.375)-arctan(50/84.85)+arctan(50/3)+arctan(50/10.61)
