Is there a special way to solve non-linear equations without using solve block?

Hi all,

I have been struggling to solve a  nonlinear equation, no matter what guess values  I use it seems Mathcad just won't solve it. Please see attached file.

I just need to find the values of P0 at t=0,0.5..5 seconds.

Thanks very much,

How about the attached.

Hi Mike,

Thanks for the effort. Unfortunately our versions of Mathcad are different so I can't try your code. I am sorry for the inconvenience. But I figured it may have been the constraints that I put. So I changed the constraints a little and I got some answers..whether the answers are right is a subject for another day
