The only way I can integrate the dr term is with trig functions, but according the the answers there is a simple way such that no trig functions are required.

Hi quantoembryo! :)

After separation of variables, your equation should be:

How would you integrate the ds term?

Can you perhaps apply something similar to the dr term?

Re: First Order Differential

The first term can be integrated with a substitution if you write and let .
