Integration:Integration is the reverse process of
differentiation. Suppose ddxf ( x )=F ( x ), then F (x) is called
ant derivative or integration of the function F ( x ) with respect to x.
In symbol, we have ā«F (x )dx=f ( x )+c
Again, if ddx [F ( x )+c ] is also equal ĀæF (x)
Formulae
1. ā« kf (x )dx=kā« f ( x )dx+c
2. ā« [ f ( x )+g ( x ) ] dx=ā« f ( x )dx+ā« g (x )dx+c
3. ā« xndx= xn+1
n+1+c ,nā ā1
4. ā« dx=x+c
5. ā« 1x dx=ln x+c
6. ā« exdx=ex+c
7. ā« eax dx= eax
a+c
8. ā« (ax+b )ndx= (ax+b )n+1
a (n+1 )+c ,nā ā1
