求解matlab绘制参数函数
y=50*cos(t)-40*cos(t+7.5*((1-cos(3.1415926*t/55))-0.25*(1-cos(2*3.1415926*t/55))+36.86);
x=50*sin(t)-40*sin(t+7.5*((1-cos(3.1415926*t/55))-0.25*(1-cos(2*3.1415926*t/55))+36.86);
就是绘制这个方程的函数图象,t是角度,从0到360
画出来了,多加了一个括号

答案

syms x y ty=50*cos(t)-40*cos(t+7.5*(1-cos(3.1415926*t/55))-0.25*(1-cos(2*3.1415926*t/55))+36.86);x=50*sin(t)-40*sin(t+7.5*((1-cos(3.1415926*t/55))-0.25*(1-cos(2*3.1415926*t/55))+36.86);ezplot(x,y,[0,2...
