Work: Calculate the value of equation 90-arctan(0.1*5)-arctan(0.2*5)-arctan(0.06*5)-arctan(12*5)+arctan(0.3*5)+arctan(2*5) .
Question type: Mathematical calculation
Solution:
90-arctan(0.1*5)-arctan(0.2*5)-arctan(0.06*5)-arctan(12*5)+arctan(0.3*5)+arctan(2*5)
=90-arctan0.5-arctan(0.2*5)-arctan(0.06*5)-arctan(12*5)+arctan(0.3*5)+arctan(2*5)
=90-arctan0.5-arctan1-arctan(0.06*5)-arctan(12*5)+arctan(0.3*5)+arctan(2*5)
=90-arctan0.5-arctan1-arctan0.3-arctan(12*5)+arctan(0.3*5)+arctan(2*5)
=90-arctan0.5-arctan1-arctan0.3-arctan60+arctan(0.3*5)+arctan(2*5)
=90-arctan0.5-arctan1-arctan0.3-arctan60+arctan1.5+arctan(2*5)
=90-arctan0.5-arctan1-arctan0.3-arctan60+arctan1.5+arctan10
=90-0.463648-arctan1-arctan0.3-arctan60+arctan1.5+arctan10
=90-0.463648-0.785398-arctan0.3-arctan60+arctan1.5+arctan10
=90-0.463648-0.785398-0.291457-arctan60+arctan1.5+arctan10
=90-0.463648-0.785398-0.291457-1.554131+arctan1.5+arctan10
=90-0.463648-0.785398-0.291457-1.554131+0.982794+arctan10
=90-0.463648-0.785398-0.291457-1.554131+0.982794+1.471128
=89.536352-0.785398-0.291457-1.554131+0.982794+1.471128
=88.750954-0.291457-1.554131+0.982794+1.471128
=88.459497-1.554131+0.982794+1.471128
=86.905366+0.982794+1.471128
=87.88816+1.471128
=89.359288
Answer:90-arctan(0.1*5)-arctan(0.2*5)-arctan(0.06*5)-arctan(12*5)+arctan(0.3*5)+arctan(2*5)=89.359288
