〖1/1算式〗
作业：求算式 0.23*1.43*1000*0.45*0.45*3.14159*(1-(sin(2*3.14159*0.23))/(2*3.14159*0.23))+(3*0.23-1.25)*270*3.848 的值.
题型：数学计算
解:
0.23*1.43*1000*0.45*0.45*3.14159*(1-(sin(2*3.14159*0.23))/(2*3.14159*0.23))+(3*0.23-1.25)*270*3.848
=0.23*1.43*1000*0.45*0.45*3.14159*(1-(sin1.445131)/(2*3.14159*0.23))+(3*0.23-1.25)*270*3.848
=0.23*1.43*1000*0.45*0.45*3.14159*(1-0.992114/(2*3.14159*0.23))+(3*0.23-1.25)*270*3.848
=0.23*1.43*1000*0.45*0.45*3.14159*(1-0.992114/1.445131)+(3*0.23-1.25)*270*3.848
=0.23*1.43*1000*0.45*0.45*3.14159*0.313478+(3*0.23-1.25)*270*3.848
=0.23*1.43*1000*0.45*0.45*3.14159*0.313478+(-0.56)*270*3.848
=0.3289*1000*0.45*0.45*3.14159*0.313478+(-0.56)*270*3.848
=328.9*0.45*0.45*3.14159*0.313478+(-0.56)*270*3.848
=148.005*0.45*3.14159*0.313478+(-0.56)*270*3.848
=66.60225*3.14159*0.313478+(-0.56)*270*3.848
=209.236963*0.313478+(-0.56)*270*3.848
=65.591185+(-0.56)*270*3.848
=65.591185+(-151.2)*3.848
=65.591185+(-581.8176)
=-516.226415
答案:0.23*1.43*1000*0.45*0.45*3.14159*(1-(sin(2*3.14159*0.23))/(2*3.14159*0.23))+(3*0.23-1.25)*270*3.848=-516.226415
