F := int(1/((-x^2+1)*(-r*x^2+1))^(1/2), x = 0 .. 1):
G := subs(r = (u2^2+u3^2)/(u1^2+u3^2), F):
Q := subs({u1 = 2.2*10^2, u2 = 0}, G):
plot(Q, u3 = -10 .. 10)
运行的时候提示
Warning, unable to evaluate the function to numeric values in the region; see the plotting command*s help page to ensure the calling sequence is correct
这是说我调用顺序有问题,谁能帮我解决下?
