Hi!

I am trying to write a question involving a second order initial value problem. The 2 conditions are

u(0) = $a

du
--(0) = $b
dx

but I am not able to code it correctly. I have tried

...
$eq2=$mathml("(d^2u)/(dx^2)+($mamb)(du)/(dx)+($ab)u=0");
$eq3=maple("printf(MathML:-ExportPresentation(u(0)=$a))");
$eq4=maple("printf(MathML:-ExportPresentation(du/dx(0)=$b))");
...

This works fine for the first condition, but I get

du
---- =
dx(0)

for the second one. Is there a way to get the "(0)" in the right place, either using "$mathml" or "printf"?

Thanks in advance for your help.
