thanks in advance

anonymous · Answer

a complicated fraction is divided into partial fractions to make integration easier
The denominator is factorised and foe each linear factor a single letter is set as the numeratpr  eg A/x+1, for  a square like (1-x)^2  two partial fractions are  written  eg
 B / 1-x and C / ((1-x)^2 and for a second degree expression like x^2 - 5 whcih cannot be factored we write Ex + D / x^2 -5.
Now we multiply all terms by the LCM of denominator to get an identity with no fractions. The values of A, B C etc can be found by substituting appropriate value of x into the identity. Also we can equate denominators  
Now we integrate each individual fraction.

cool. Thanks

ok - try an easy - split  3x / (x+2)^2 into partial fractions. You need to practice this stuff to become proficient.
