Work: Calculate the value of equation -90-arctan(0.1*0.6)-arctan(0.01*0.6)-arctan(0.6/0.375)-arctan(0.6/84.85)+arctan(0.6/3)+arctan(0.6/10.61) .
Question type: Mathematical calculation
Solution:
-90-arctan(0.1*0.6)-arctan(0.01*0.6)-arctan(0.6/0.375)-arctan(0.6/84.85)+arctan(0.6/3)+arctan(0.6/10.61)
=-90-arctan0.06-arctan(0.01*0.6)-arctan(0.6/0.375)-arctan(0.6/84.85)+arctan(0.6/3)+arctan(0.6/10.61)
=-90-arctan0.06-arctan0.006-arctan(0.6/0.375)-arctan(0.6/84.85)+arctan(0.6/3)+arctan(0.6/10.61)
=-90-arctan0.06-arctan0.006-arctan1.6-arctan(0.6/84.85)+arctan(0.6/3)+arctan(0.6/10.61)
=-90-arctan0.06-arctan0.006-arctan1.6-arctan0.007071+arctan(0.6/3)+arctan(0.6/10.61)
=-90-arctan0.06-arctan0.006-arctan1.6-arctan0.007071+arctan0.2+arctan(0.6/10.61)
=-90-arctan0.06-arctan0.006-arctan1.6-arctan0.007071+arctan0.2+arctan0.05655
=-90-0.059928-arctan0.006-arctan1.6-arctan0.007071+arctan0.2+arctan0.05655
=-90-0.059928-0.006-arctan1.6-arctan0.007071+arctan0.2+arctan0.05655
=-90-0.059928-0.006-1.012197-arctan0.007071+arctan0.2+arctan0.05655
=-90-0.059928-0.006-1.012197-0.007071+arctan0.2+arctan0.05655
=-90-0.059928-0.006-1.012197-0.007071+0.197396+arctan0.05655
=-90-0.059928-0.006-1.012197-0.007071+0.197396+0.05649
=-90.059928-0.006-1.012197-0.007071+0.197396+0.05649
=-90.065928-1.012197-0.007071+0.197396+0.05649
=-91.078125-0.007071+0.197396+0.05649
=-91.085196+0.197396+0.05649
=-90.8878+0.05649
=-90.83131
Answer:-90-arctan(0.1*0.6)-arctan(0.01*0.6)-arctan(0.6/0.375)-arctan(0.6/84.85)+arctan(0.6/3)+arctan(0.6/10.61)=-90.83131
