Work: Calculate the value of equation arctan(3*0.237)-90-arctan(6*0.237)-arctan(10*0.237)-arctan(4*0.237/25) .
Question type: Mathematical calculation
Solution:
arctan(3*0.237)-90-arctan(6*0.237)-arctan(10*0.237)-arctan(4*0.237/25)
=arctan0.711-90-arctan(6*0.237)-arctan(10*0.237)-arctan(4*0.237/25)
=arctan0.711-90-arctan1.422-arctan(10*0.237)-arctan(4*0.237/25)
=arctan0.711-90-arctan1.422-arctan2.37-arctan(4*0.237/25)
=arctan0.711-90-arctan1.422-arctan2.37-arctan0.03792
=0.61807-90-arctan1.422-arctan2.37-arctan0.03792
=0.61807-90-0.957903-arctan2.37-arctan0.03792
=0.61807-90-0.957903-1.17152-arctan0.03792
=0.61807-90-0.957903-1.17152-0.037902
=-89.38193-0.957903-1.17152-0.037902
=-90.339833-1.17152-0.037902
=-91.511353-0.037902
=-91.549255
Answer:arctan(3*0.237)-90-arctan(6*0.237)-arctan(10*0.237)-arctan(4*0.237/25)=-91.549255
