对一个积分结果绘图,积分后给了一个函数,可用函数绘图确出现错误,意思好像说超出定义域,绘图失败
可是自变量根本没超出定义域啊?
大家帮忙看看吧,谢谢!
参数
v = 0.187
r = 1/v
V = 0.112
R = 1/V
a = 0.391
b = 1.51
y = 2.0
c = y/v
m = r/R
d = c/m
积分
p[t_]=Integrate[exp(c*x)*a^2*(V-x)/(V-b*(V-x))^2*(1-y/V*x/2/x*(V-x)), {x,V,t}]
绘图
Plot[p[t], {t, 0.111, 0.135}]
出现错误
Plot::"plnr": "\!\(p[t]\) is not a machine-size real number at \!\(t\) = \
\!\(0.111000001`\)."
General::"stop": "Further output of \!\(Plot :: \"plnr\"\) will be suppressed \
during this calculation." |
