作业:求算式 0.32*14.3*1000*3.1416*0.4*0.4*(1-sin(2*180*0.32)/(2*3.1415926*0.32))+(3*0.32-1.25)*300*510 的值.
题型:数学计算
解:
0.32*14.3*1000*3.1416*0.4*0.4*(1-sin(2*180*0.32)/(2*3.1415926*0.32))+(3*0.32-1.25)*300*510
=0.32*14.3*1000*3.1416*0.4*0.4*(1-sin115.2/(2*3.1415926*0.32))+(3*0.32-1.25)*300*510
=0.32*14.3*1000*3.1416*0.4*0.4*(1-sin115.2/2.010619)+(3*0.32-1.25)*300*510
=0.32*14.3*1000*3.1416*0.4*0.4*0.571345+(3*0.32-1.25)*300*510
=0.32*14.3*1000*3.1416*0.4*0.4*0.571345+(-0.29)*300*510
=4.576*1000*3.1416*0.4*0.4*0.571345+(-0.29)*300*510
=4576*3.1416*0.4*0.4*0.571345+(-0.29)*300*510
=14375.9616*0.4*0.4*0.571345+(-0.29)*300*510
=5750.38464*0.4*0.571345+(-0.29)*300*510
=2300.153856*0.571345+(-0.29)*300*510
=1314.181405+(-0.29)*300*510
=1314.181405+(-87)*510
=1314.181405+(-44370)
