Work: Calculate the value of equation arctan(0.5×11.92)-90-arctan(10×11.92)-arctan(0.03×11.92)-arctan(0.0047×11.92)+180 .
Question type: Mathematical calculation
Solution:
arctan(0.5×11.92)-90-arctan(10×11.92)-arctan(0.03×11.92)-arctan(0.0047×11.92)+180
=arctan5.96-90-arctan(10×11.92)-arctan(0.03×11.92)-arctan(0.0047×11.92)+180
=arctan5.96-90-arctan119.2-arctan(0.03×11.92)-arctan(0.0047×11.92)+180
=arctan5.96-90-arctan119.2-arctan0.3576-arctan(0.0047×11.92)+180
=arctan5.96-90-arctan119.2-arctan0.3576-arctan0.056024+180
=1.40456-90-arctan119.2-arctan0.3576-arctan0.056024+180
=1.40456-90-1.562407-arctan0.3576-arctan0.056024+180
=1.40456-90-1.562407-0.343429-arctan0.056024+180
=1.40456-90-1.562407-0.343429-0.055965+180
=-88.59544-1.562407-0.343429-0.055965+180
=-90.157847-0.343429-0.055965+180
=-90.501276-0.055965+180
=-90.557241+180
=89.442759
Answer:arctan(0.5×11.92)-90-arctan(10×11.92)-arctan(0.03×11.92)-arctan(0.0047×11.92)+180=89.442759
