Work: Calculate the value of equation 90-arctan(0.1*91)-arctan(0.01*91)+arctan(0.052*91)-arctan(0.004*91) .
Question type: Mathematical calculation
Solution:
90-arctan(0.1*91)-arctan(0.01*91)+arctan(0.052*91)-arctan(0.004*91)
=90-arctan9.1-arctan(0.01*91)+arctan(0.052*91)-arctan(0.004*91)
=90-arctan9.1-arctan0.91+arctan(0.052*91)-arctan(0.004*91)
=90-arctan9.1-arctan0.91+arctan4.732-arctan(0.004*91)
=90-arctan9.1-arctan0.91+arctan4.732-arctan0.364
=90-1.461345-arctan0.91+arctan4.732-arctan0.364
=90-1.461345-0.738313+arctan4.732-arctan0.364
=90-1.461345-0.738313+1.362533-arctan0.364
=90-1.461345-0.738313+1.362533-0.349092
=88.538655-0.738313+1.362533-0.349092
=87.800342+1.362533-0.349092
=89.162875-0.349092
=88.813783
Answer:90-arctan(0.1*91)-arctan(0.01*91)+arctan(0.052*91)-arctan(0.004*91)=88.813783
