Work: Calculate the value of equation arctan(17.9*0.55)-90-arctan(137.4*0.55)-arctan(0.55)-arctan(0.5*0.55) .
Question type: Mathematical calculation
Solution:
arctan(17.9*0.55)-90-arctan(137.4*0.55)-arctan(0.55)-arctan(0.5*0.55)
=arctan9.845-90-arctan(137.4*0.55)-arctan(0.55)-arctan(0.5*0.55)
=arctan9.845-90-arctan75.57-arctan(0.55)-arctan(0.5*0.55)
=arctan9.845-90-arctan75.57-arctan0.55-arctan(0.5*0.55)
=arctan9.845-90-arctan75.57-arctan0.55-arctan0.275
=1.469569-90-arctan75.57-arctan0.55-arctan0.275
=1.469569-90-1.557564-arctan0.55-arctan0.275
=1.469569-90-1.557564-0.502843-arctan0.275
=1.469569-90-1.557564-0.502843-0.268366
=-88.530431-1.557564-0.502843-0.268366
=-90.087995-0.502843-0.268366
=-90.590838-0.268366
=-90.859204
Answer:arctan(17.9*0.55)-90-arctan(137.4*0.55)-arctan(0.55)-arctan(0.5*0.55)=-90.859204
