Question type: Mathematical calculation
Solution:
-90-arctan(0.12×1.3)-arctan(0.02×1.3)-arctan(1/0.205×1.3)-arctan(1/23.894×1.3)+arctan(1/1.3×1.3)+arctan(1/7.073×1.3)
=-90-arctan0.156-arctan(0.02×1.3)-arctan(1/0.205×1.3)-arctan(1/23.894×1.3)+arctan(1/1.3×1.3)+arctan(1/7.073×1.3)
=-90-arctan0.156-arctan0.026-arctan(1/0.205×1.3)-arctan(1/23.894×1.3)+arctan(1/1.3×1.3)+arctan(1/7.073×1.3)
=-90-arctan0.156-arctan0.026-arctan6.341464-arctan(1/23.894×1.3)+arctan(1/1.3×1.3)+arctan(1/7.073×1.3)
=-90-arctan0.156-arctan0.026-arctan6.341464-arctan0.054408+arctan(1/1.3×1.3)+arctan(1/7.073×1.3)
=-90-arctan0.156-arctan0.026-arctan6.341464-arctan0.054408+arctan1+arctan(1/7.073×1.3)
=-90-arctan0.156-arctan0.026-arctan6.341464-arctan0.054408+arctan1+arctan0.183798
=-90-0.154753-arctan0.026-arctan6.341464-arctan0.054408+arctan1+arctan0.183798
=-90-0.154753-0.025994-arctan6.341464-arctan0.054408+arctan1+arctan0.183798
=-90-0.154753-0.025994-1.414392-arctan0.054408+arctan1+arctan0.183798
=-90-0.154753-0.025994-1.414392-0.054354+arctan1+arctan0.183798
=-90-0.154753-0.025994-1.414392-0.054354+0.785398+arctan0.183798
=-90-0.154753-0.025994-1.414392-0.054354+0.785398+0.181769
=-90.154753-0.025994-1.414392-0.054354+0.785398+0.181769
=-90.180747-1.414392-0.054354+0.785398+0.181769
=-91.595139-0.054354+0.785398+0.181769
=-91.649493+0.785398+0.181769
=-90.864095+0.181769
=-90.682326
Answer:-90-arctan(0.12×1.3)-arctan(0.02×1.3)-arctan(1/0.205×1.3)-arctan(1/23.894×1.3)+arctan(1/1.3×1.3)+arctan(1/7.073×1.3)=-90.682326
