integration using partial fractions

Integration by partial fractions

Integration formulae

first of all check if degree of numerator is less than degree of denominator
else perform long division.

---------------------------------------

you might then have to restore to completion of squares in some cases after the manipulation
in some cases the manipulation can be done through inspection

Examples

* ∫ dx / [ (x-2) (1 + x²)]
integral using partial fractions

*integral of (x² +1) / [(x+3)(x-1)²]
integration using partial fraction

telescoping series

simplify 1/12 + 1/20 +1/30 +1/42 +1/9900 using partial fraction
try to express in the form 1 / n(n+1)
use partial fraction to split into two terms
then sum

integral of (5x^3 + 8x^2 + 36x + 36) / (x^4 + 9x^2)

integral of (5x^3 + 8x^2 + 36x + 36) / (x^4 + 9x^2)
first do the partial fraction decomposition
refer partial fraction decomposition
then split the (x+4) /( x² +9) into two terms
the first one can be manipulated into u' / u form

partial fractions

put 1/ [x(1 + x ² )] into partial fractions

other examples
put into partial fraction 1 / {(x^3) + 1 } -----> (partial fractions problem)

put 1/[ (x)(x-2)(2x-1)] into partial fractions ----------partial fraction
