Work: Calculate the value of equation -90-arctan30-arctan3-arctan(300/0.375)-arctan(300/84.85)+arctan(300/3)+arctan(300/10.61) .
Question type: Mathematical calculation
Solution:
-90-arctan30-arctan3-arctan(300/0.375)-arctan(300/84.85)+arctan(300/3)+arctan(300/10.61)
=-90-arctan30-arctan3-arctan800-arctan(300/84.85)+arctan(300/3)+arctan(300/10.61)
=-90-arctan30-arctan3-arctan800-arctan3.535651+arctan(300/3)+arctan(300/10.61)
=-90-arctan30-arctan3-arctan800-arctan3.535651+arctan100+arctan(300/10.61)
=-90-arctan30-arctan3-arctan800-arctan3.535651+arctan100+arctan28.275212
=-90-1.537475-arctan3-arctan800-arctan3.535651+arctan100+arctan28.275212
=-90-1.537475-1.249046-arctan800-arctan3.535651+arctan100+arctan28.275212
=-90-1.537475-1.249046-1.569546-arctan3.535651+arctan100+arctan28.275212
=-90-1.537475-1.249046-1.569546-1.295162+arctan100+arctan28.275212
=-90-1.537475-1.249046-1.569546-1.295162+1.560797+arctan28.275212
=-90-1.537475-1.249046-1.569546-1.295162+1.560797+1.535444
=-91.537475-1.249046-1.569546-1.295162+1.560797+1.535444
=-92.786521-1.569546-1.295162+1.560797+1.535444
=-94.356067-1.295162+1.560797+1.535444
=-95.651229+1.560797+1.535444
=-94.090432+1.535444
=-92.554988
Answer:-90-arctan30-arctan3-arctan(300/0.375)-arctan(300/84.85)+arctan(300/3)+arctan(300/10.61)=-92.554988
