Integrals

Compute integrals with Integrate:

In[1]:=

⨯

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]:=

⨯

\[Integral]8 x^4 \[DifferentialD]x

Out[2]=

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

In[1]:=

⨯

\!\(
\*SubsuperscriptBox[\(\[Integral]\), \(0\), \(\[Pi]\)]\(Sin[
   x] \[DifferentialD]x\)\)

Out[1]=

Use NIntegrate for a numeric approximation:

In[2]:=

⨯

NIntegrate[x^3 Sin[x] + 2 Log[3 x]^2, {x, 0, Pi}]

Out[2]=
