Work: Calculate the value of equation -90-2*arctan(12.79/25)-arctan(12.79)+arctan(12.79/2) .
Question type: Mathematical calculation
Solution:
-90-2*arctan(12.79/25)-arctan(12.79)+arctan(12.79/2)
=-90-2*arctan0.5116-arctan(12.79)+arctan(12.79/2)
=-90-2*arctan0.5116-arctan12.79+arctan(12.79/2)
=-90-2*arctan0.5116-arctan12.79+arctan6.395
=-90-2*0.472884-arctan12.79+arctan6.395
=-90-2*0.472884-1.492769+arctan6.395
=-90-2*0.472884-1.492769+1.41568
=-90-0.945768-1.492769+1.41568
=-90.945768-1.492769+1.41568
=-92.438537+1.41568
=-91.022857
Answer:-90-2*arctan(12.79/25)-arctan(12.79)+arctan(12.79/2)=-91.022857
