# Differential Equation...... watch

1. I need help on the following question:

"Find general solution of the following differential equation:

x.dx/dt = (x^2 + 4)ln(t)"

I cant remeber how to do this, hopefully someone can help.

Thanks.

3. It's separable.
4. It's separable.
5. do you mean the following:

int x/(x^2 +4)dx = int ln(t)dt ???????
6. do you mean the following:

int x/(x^2 +4)dx = int ln(t)dt ???????

do you mean the following:

int x/(x^2 +4)dx = int ln(t)dt ???????
Yep, they do.

--------------

You can integrate ln(t) by parts.
