〖1/1算式〗
作业：求算式 0.31*1.43*1000*0.45*0.45*3.14159*(1-(sin(2*3.14159*0.31))/(2*3.14159*0.31))+(3*0.31-1.25)*270*3.848 的值.
题型：数学计算
解:
0.31*1.43*1000*0.45*0.45*3.14159*(1-(sin(2*3.14159*0.31))/(2*3.14159*0.31))+(3*0.31-1.25)*270*3.848
=0.31*1.43*1000*0.45*0.45*3.14159*(1-(sin1.947786)/(2*3.14159*0.31))+(3*0.31-1.25)*270*3.848
=0.31*1.43*1000*0.45*0.45*3.14159*(1-0.929777/(2*3.14159*0.31))+(3*0.31-1.25)*270*3.848
=0.31*1.43*1000*0.45*0.45*3.14159*(1-0.929777/1.947786)+(3*0.31-1.25)*270*3.848
=0.31*1.43*1000*0.45*0.45*3.14159*0.522649+(3*0.31-1.25)*270*3.848
=0.31*1.43*1000*0.45*0.45*3.14159*0.522649+(-0.32)*270*3.848
=0.4433*1000*0.45*0.45*3.14159*0.522649+(-0.32)*270*3.848
=443.3*0.45*0.45*3.14159*0.522649+(-0.32)*270*3.848
=199.485*0.45*3.14159*0.522649+(-0.32)*270*3.848
=89.76825*3.14159*0.522649+(-0.32)*270*3.848
=282.015037*0.522649+(-0.32)*270*3.848
=147.394877+(-0.32)*270*3.848
=147.394877+(-86.4)*3.848
=147.394877+(-332.4672)
=-185.072323
答案:0.31*1.43*1000*0.45*0.45*3.14159*(1-(sin(2*3.14159*0.31))/(2*3.14159*0.31))+(3*0.31-1.25)*270*3.848=-185.072323
