I'm using maple 13.

The expression that I paste below is quite large and subsequent expressions are also swelling. This is causing maple to slow down and in some instances I get a message saying the kernel has disconnected (maple just times out) I want a way to programmatically reduce the size of the output. I have tried simplify(expr,size) and this has helped some. I don't want to use simplify(expr,symbolic) because of the presence of the square roots. Is there...

 I have the following equation that I want to plot for theta and t with other parameter values in the equation fixed as below. But when I try to animate the solution I get an 'unable to plot' error message. What can I do to plot the equation, U(theta, t) below.

 U(theta, t) := 1/2/Pi+Q*sin(k*theta)+P*sin(m*theta)+1/4*(-I*Q*exp(1/2*k*(-sigma^2*k+2*I*theta...

I just wondered if there was a similar rule for sine.

> I found this information and code quite useful. Now my set t1 changes slightly to include I and -I. I also set up conditionl statements to extract the right elements according to the criteria on the value of beta*Q as adviced previously. I then test this out using the values for (beta,Q) as (1,1), (-1,1),(0,1).

When beta*Q is positive (one in this case) I is not selected...

I find the singularities of an expression by using the function singular and the result of this is what I call t1a below.
