Integration of polynomials
How do you find the anti-derivative using
the reverse of the power rule?
Methods (substitution, integraion by parts,
integration by partial fractions)
Word File with 2 ORIGINAL Examples of
substitution(one must be trig)
Remember the first way you
learned to derive
 F(x)=2x3
 F’(x)=2*3x(3-1)
 F’(x)=6x2
 The power rule derives a polynomial or
variable by multiplying the variable’s
coefficient by the exponent and
subtracting one from the exponent
To integrate a polynomial you
do the reverse
Multiply coefficient by
exponent
Subtract one from the
exponent
Add one to the exponentDivide the coefficient
by the NEW exponent
So to integrate 6x2 you
 Add one to the exponent of 2 giving you
x cubed
 And divide the coefficient, six, by the
new exponent three giving you:
 2x3
