Mathematica 应用

用数学软件Mathematica做微积分   http://xuxzmail.blog.163.com/blog/static/25131916201084112726584/  

用数学软件Mathematica做线性代数  http://xuxzmail.blog.163.com/blog/static/25131916201084113139224/

 

用Mathematica画显函数曲线  

 

 f[x_]:=x^3-x^2-x+1;

Plot[f[x],{x,-2,2}]

  

 

 

增加一些设置:

f[x_]:=x^3-x^2-x+1;

Plot[f[x],{x,-2,2},PlotStyle->{Red,Thickness[0.01]},AspectRatio->Automatic,Ticks->{Range[-2,2,1],Range[-5,3,1]}]

 

 

 

 

 

 

f[x_]:=Piecewise[{{Exp[x],x<0},{x^2,1>x>=0},{Sin[x],x>=1}}];

Plot[f[x],{x,-2,2}]

 

 

增加一些设置:

f[x_]:=Piecewise[{{Exp[x],x<0},{x^2,1>x>= 0},{Sin[x],x>= 1}}];

Plot[f[x],{x,-2,2},PlotStyle->{Red,AbsoluteThickness[3]},Exclusions->{0,1},PlotRange->{{-2,2},{-0.2,1.3}},AspectRatio->Automatic,Ticks->{Range[-3,3,0.5],Range[-3,3,0.5]},AxesOrigin->{0,0}]
