please... i need a help in integrating the partial fractions
i can't proceed to the integration part if i don't understand the patter in finding the constant...
that is...
if the given is:
ʃ ( (x^5+1) / ((x^3)(x+1)) )dx
then;
ʃ ( x-2 + ( 4x^3+1 ) / ( x^4 + 2x^3) )
ʃ ( x-2 + ( 4x^3 + 1 ) / ( x^3 (x + 2 ) )
ʃ ( x-2 + A/x + B/x^2 + C/x^3 + D/x+2)
Ax^2(x+2) + Bx(x+2) + C(x+2) + D(x^3) = 4x^3 + 1 ----- i don't know what going on
in this part
