WHY YOU STILL CAN'T SOLVE THAT PARTIAL FRACTION INTEGRAL.
Calc students across the world (durp.. I was an online tutor) are seduced by the simplicity of partial fraction decomposition only to realize they only know the process for linear terms in the denominator. Here is an example with the incorrect set-up, and another with the correct set-up:
(x+1)^2}=\frac{A}{(x^2+2)}+\frac{B}{(x+1)^2} "\frac{1}{(x^2+2)(x+1)^2}=\frac{A}{(x^2+2)}+\frac{B}{(x+1)^2}")
CORRECT SET-UP:
(x+1)^2}=\frac{Ax+B}{(x^2+2)}+\frac{C}{(x+1)^2}+\frac{D}{(x+1)} "\frac{1}{(x^2+2)(x+1)^2}=\frac{Ax+B}{(x^2+2)}+\frac{C}{(x+1)^2}+\frac{D}{(x+1)}")
