Work: Calculate the value of equation 395.195×(tan(45-15.079/2)*tan(45-15.079/2))-2×14.352×tan(45-15.079/2) .
Question type: Mathematical calculation
Solution:
395.195×(tan(45-15.079/2)*tan(45-15.079/2))-2×14.352×tan(45-15.079/2)
=395.195×(tan37.4605*tan(45-15.079/2))-2×14.352×tan(45-15.079/2)
=395.195×(tan37.4605*tan37.4605)-2×14.352×tan(45-15.079/2)
=395.195×0.059169-2×14.352×tan(45-15.079/2)
=395.195×0.059169-2×14.352×tan37.4605
=395.195×0.059169-2×14.352×-0.243246
=23.383293-2×14.352×(-0.243246)
=23.383293-28.704×(-0.243246)
=23.383293-(-6.982133)
=30.365426
Answer:395.195×(tan(45-15.079/2)*tan(45-15.079/2))-2×14.352×tan(45-15.079/2)=30.365426
