We have to find

Let us first find least common multiplier of 5 and 4. Note that prime factorization of 5 is 5. Also, prime factorization of 4 is 2*2.

Therefore, least common multiplier of 5 and 4 is

Multiply numerator and denominator of the fraction such a way that the denominator of each fraction become 20. We get

Partial Fraction Decomposition??

How do I separate this by partial fraction decomposition?

$\int \frac{1}{u({u}^{2}+1)}du$

I've used the normal technique and got to:

$1=A({u}^{2}+1)+B(u)$

$1=A({u}^{2}+1)+B(u)$

and $A=1$ if $u=0$ BUT how do I find $B$ now? because I can't make ${u}^{2}+1$ equal to 0.
