mathematica作图的错误是
Plot[Normal[Series[Sin[x],{x,3,3}]],{x,1,5}]为什么做不出图,错误提示为General::ivar:1.0000817142857144` is not a valid variable.
General::stop:Further output of General::ivar will be suppressed during this calculation.

在Normal前面加个Evaluate就行了 :
Plot[Evaluate@Normal[Series[Sin[x],{x,3,3}]],{x,1,5}]
