⨯ 
Integrate[8 x^4, x]
Out[1]=

Or type ESCinttESC for a fillable mathematical expression:

(For more information on fillable expressions, see Mathematical Typesetting.)
In[2]:=
Click for copyable input
⨯ 
\[Integral]8 x^4 \[DifferentialD]x
Out[2]=

For definite integrals, type ESCdinttESC and specify upper and lower limits:

In[1]:=
Click for copyable input
⨯ 
\!\(
\*SubsuperscriptBox[\(\[Integral]\), \(0\), \(\[Pi]\)]\(Sin[
   x] \[DifferentialD]x\)\)
Out[1]=

Use NIntegrate for a numeric approximation:

In[2]:=
Click for copyable input
⨯ 
NIntegrate[x^3 Sin[x] + 2 Log[3 x]^2, {x, 0, Pi}]
Out[2]=
