ok just trying to integrat something here

-[(tan(theta)) dtheta]/[sec(theta) (2cos(theta)-1)^(0.5) (1-cos(theta))] = (sqrt(Mgh/A)) t

and get to sec(theta) = 1 + sech (sqrt(Mgh/A)) t

any advice?

You are supposed ...

You are supposed to

1. Use Maple syntax (as nobody likes to type in your problem)

2. Ask a question ("any advice?" might be answered by "sure, have a coffee!")

3. It does not hurt to speak in complete sentences

And in most places some 'magic word' is not a bad idea ...

So please give your problem a new chance, yes?

Here is a start

-int((tan(theta))/(sec(theta)*(2*cos(theta)-1)^(1/2)*(1-cos(theta))),theta) = (sqrt(Mgh/A))*t;

combine(%);

Now you still need to convert a difference of arctanh's in to arcsech
