请问maple里是怎么画圆的
plot(1/4 = x/(x^2+y^2));
Error,invalid input:plot expects its 1st argument,p,to be of type {array,list,rtable,set,algebraic,procedure,And(`module`,appliable)},but received 1/4 = x/(x^2+y^2)
plot(x^2+y^2 = 4);
Error,invalid input:plot expects its 1st argument,p,to be of type {array,list,rtable,set,algebraic,procedure,And(`module`,appliable)},but received x^2+y^2 = 4

隐函数和显函数画图有所不同.
试下implicitplot函数
with(plots);
implicitplot(x^2+y^2 = 4,x = -2 ..2,y = -2 ..2);
with(plots, implicitplot);
implicitplot(x^2+y^2 = 4, x = -2 .. 2, y = -2 .. 2);
