Work: Calculate the value of equation 395.195×(tan(45-14.85/2)*tan(45-14.85/2))-2×14.12×tan(45-14.85/2) .
Question type: Mathematical calculation
Solution:
395.195×(tan(45-14.85/2)*tan(45-14.85/2))-2×14.12×tan(45-14.85/2)
=395.195×(tan37.575*tan(45-14.85/2))-2×14.12×tan(45-14.85/2)
=395.195×(tan37.575*tan37.575)-2×14.12×tan(45-14.85/2)
=395.195×0.015563-2×14.12×tan(45-14.85/2)
=395.195×0.015563-2×14.12×tan37.575
=395.195×0.015563-2×14.12×-0.124753
=6.15042-2×14.12×(-0.124753)
=6.15042-28.24×(-0.124753)
=6.15042-(-3.523025)
=9.673445
Answer:395.195×(tan(45-14.85/2)*tan(45-14.85/2))-2×14.12×tan(45-14.85/2)=9.673445
