Work: Calculate the value of equation -90+arctan(1.5/0.1875)-arctan(1.5/0.028)-2*arctan(1.5/12) .
Question type: Mathematical calculation
Solution:
-90+arctan(1.5/0.1875)-arctan(1.5/0.028)-2*arctan(1.5/12)
=-90+arctan8-arctan(1.5/0.028)-2*arctan(1.5/12)
=-90+arctan8-arctan53.571429-2*arctan(1.5/12)
=-90+arctan8-arctan53.571429-2*arctan0.125
=-90+1.446441-arctan53.571429-2*arctan0.125
=-90+1.446441-1.552132-2*arctan0.125
=-90+1.446441-1.552132-2*0.124355
=-90+1.446441-1.552132-0.24871
=-88.553559-1.552132-0.24871
=-90.105691-0.24871
=-90.354401
Answer:-90+arctan(1.5/0.1875)-arctan(1.5/0.028)-2*arctan(1.5/12)=-90.354401
