还在讨论呢,

str=sym(maple('eliminate({y-600*sin(t),sin(x)*sin(t)+cos(x)*cos(t)+sin(t)-cos(t)},{t})'));
y=sqrt(sym(maple('solve',str,'y^2')));
x=0:0.05:4*pi;
y1=subs(y);
y2=subs(-y);
plot(x,y ...

LoopConstant x=[0:0.2:15];
ParameterDomain = [0,];
PlotLoopData x[x],y;
Function sin(x)*sin(t)+cos(x)*cos(t)+sin(t)-cos(t)=0;
           y=600*sin(t);

用1stOpt帮你画一个，参考下：

LoopConstant x=;
ParameterDomain = ;
PlotLoopData x,y;
Function sin(x)*sin(t)+cos(x)*cos(t)+sin(t)-cos(t)=0;
           y=600*sin(t);
