为什么不出曲线啊 晕死.

Answer 1

我知道了.
syms x2 t;
f=1.06*(3.397+2.3982/(1-0.09311/x2/x2)+2.164/(1-950/x2/x2))/x2+(1-1.06/x2)*(3.397+2.3982/(1-0.09311*(1/1.06-1/x2)^2)+2.164/(1-950*(1/1.06-1/x2)^2))-2.4521*2.399/((2.4521*sin(t))^2+(2.399*cos(t))^2)
t=-pi:pi;
f1=subs(f)
for k=1:length(f1)
x2=solve(f1(k))
end
运行结果：
x2 =
