Work: Calculate the value of equation 90+arctan(0.352*2.2)-arctan(2.2)-arctan(0.25*2.2)-arctan(0.11*2.2) .
Question type: Mathematical calculation
Solution:
90+arctan(0.352*2.2)-arctan(2.2)-arctan(0.25*2.2)-arctan(0.11*2.2)
=90+arctan0.7744-arctan(2.2)-arctan(0.25*2.2)-arctan(0.11*2.2)
=90+arctan0.7744-arctan2.2-arctan(0.25*2.2)-arctan(0.11*2.2)
=90+arctan0.7744-arctan2.2-arctan0.55-arctan(0.11*2.2)
=90+arctan0.7744-arctan2.2-arctan0.55-arctan0.242
=90+0.658935-arctan2.2-arctan0.55-arctan0.242
=90+0.658935-1.144169-arctan0.55-arctan0.242
=90+0.658935-1.144169-0.502843-arctan0.242
=90+0.658935-1.144169-0.502843-0.237435
=90.658935-1.144169-0.502843-0.237435
=89.514766-0.502843-0.237435
=89.011923-0.237435
=88.774488
Answer:90+arctan(0.352*2.2)-arctan(2.2)-arctan(0.25*2.2)-arctan(0.11*2.2)=88.774488
