How do I integrate this?
constant(1 z/[sqrt (z^2 + constant^2)]
i know i can take the constant out so I have
constant * integral 1 z/[sqrt (z^2 + constant^2)]
and I know the integral of
z/[sqrt (z^2 + constant^2)] is
[ln z^2 + constant^2]/2
I just need to know in general how to separate the 1 + , i.e.
integral of 1 + f(x) = ?

sorry i meant 1 f(x)
1, not 1+

is it just integral 1 + integral f(x)
and the integral 1 = x?

Yes, the integral of 1(*dx) is just x.
