Hi guys,
I have a problem trying to calculate the integral of this function:
$\displaystyle ln(h/z) $
This function is part of a physics problem, where h is a constant that determines the height.
In the solutions, the integral is supposed to be $\displaystyle z ln(h/z) + z $
I know that the integral of ln(x) is x(ln(x)-1)
What I got from calculating this function with the formula is:
$\displaystyle (-z ln(z)+z)/h $
I don't understand how to get to the solution $\displaystyle z ln(h1/z) + z $
