lingo 求解最小值目标 min 2*200/(1.5*sin(x1))+760/(1.5*sin(x2))约束 2*(1.5_数学解答

lingo 求解最小值目标 min 2*200/(1.5*sin(x1))+760/(1.5*sin(x2))
约束 2*(1.5*cos(x1)+1.47)*(200/(1.5*sin(x1)))+(1.5*cos(x2)+2.11)*(760/(1.5*sin(x2)))=1000;
pi/2pi/2

解答

pi如果是表示π,请加pi=3.1415926;因为lingo中没有表示π的常量min=2*200/(1.5*@sin(x1))+760/(1.5*@sin(x2));2*(1.5*@cos(x1)+1.47)*(200/(1.5*@sin(x1)))+(1.5*@cos(x2)+2.11)*(760/(1.5*@sin(x2)))=1000;pi/2...
