Work: Calculate the value of equation 396.73×(tan(45-15.055/2)*tan(45-15.055/2))-2×13.935×tan(45-15.055/2) .
Question type: Mathematical calculation
Solution:
396.73×(tan(45-15.055/2)*tan(45-15.055/2))-2×13.935×tan(45-15.055/2)
=396.73×(tan37.4725*tan(45-15.055/2))-2×13.935×tan(45-15.055/2)
=396.73×(tan37.4725*tan37.4725)-2×13.935×tan(45-15.055/2)
=396.73×0.053163-2×13.935×tan(45-15.055/2)
=396.73×0.053163-2×13.935×tan37.4725
=396.73×0.053163-2×13.935×-0.230572
=21.091357-2×13.935×(-0.230572)
=21.091357-27.87×(-0.230572)
=21.091357-(-6.426042)
=27.517399
Answer:396.73×(tan(45-15.055/2)*tan(45-15.055/2))-2×13.935×tan(45-15.055/2)=27.517399
