Work: Calculate the value of equation 180-90-arctan(0.5*7.56)-arctan(0.1*7.56)-arctan(0.023*7.56)+arctan(0.23*7.56) .
Question type: Mathematical calculation
Solution:
180-90-arctan(0.5*7.56)-arctan(0.1*7.56)-arctan(0.023*7.56)+arctan(0.23*7.56)
=180-90-arctan3.78-arctan(0.1*7.56)-arctan(0.023*7.56)+arctan(0.23*7.56)
=180-90-arctan3.78-arctan0.756-arctan(0.023*7.56)+arctan(0.23*7.56)
=180-90-arctan3.78-arctan0.756-arctan0.17388+arctan(0.23*7.56)
=180-90-arctan3.78-arctan0.756-arctan0.17388+arctan1.7388
=180-90-1.312171-arctan0.756-arctan0.17388+arctan1.7388
=180-90-1.312171-0.64733-arctan0.17388+arctan1.7388
=180-90-1.312171-0.64733-0.172159+arctan1.7388
=180-90-1.312171-0.64733-0.172159+1.04888
=90-1.312171-0.64733-0.172159+1.04888
=88.687829-0.64733-0.172159+1.04888
=88.040499-0.172159+1.04888
=87.86834+1.04888
=88.91722
Answer:180-90-arctan(0.5*7.56)-arctan(0.1*7.56)-arctan(0.023*7.56)+arctan(0.23*7.56)=88.91722
