Work: Calculate the value of equation -90+arctan(0.046/0.3)-arctan(0.046/0.046)-2*arctan(0.046/7.5) .
Question type: Mathematical calculation
Solution:
-90+arctan(0.046/0.3)-arctan(0.046/0.046)-2*arctan(0.046/7.5)
=-90+arctan0.153333-arctan(0.046/0.046)-2*arctan(0.046/7.5)
=-90+arctan0.153333-arctan1-2*arctan(0.046/7.5)
=-90+arctan0.153333-arctan1-2*arctan0.006133
=-90+0.152148-arctan1-2*arctan0.006133
=-90+0.152148-0.785398-2*arctan0.006133
=-90+0.152148-0.785398-2*0.006133
=-90+0.152148-0.785398-0.012266
=-89.847852-0.785398-0.012266
=-90.63325-0.012266
=-90.645516
Answer:-90+arctan(0.046/0.3)-arctan(0.046/0.046)-2*arctan(0.046/7.5)=-90.645516
