How do you integrate #int (3x) / (x^2 * (x^2+1) )# using partial fractions?
The answer is
The expression needs some simplification
Now we can perform the decomposition into partial fractions
The denominators are the same, we compare the numerators
the integral is
The second integral is done by substutution
Putting it all together,
Resprcted Narad T. has solved the Problem using Partial
Fractions, as is reqd. to be done in that fashion.
