need help with a diff. eqn. solution

[mechanical1]

I cant figure out how to solve this error:
F:\diffequ1.cpp(41) : error C2660: 'eqn' : function does not take 2 parameters
Error executing cl.exe.

this is my command....
{
ynew=yo+eqn(xo,yo)*dx;
x=xo+dx;
return;
}

So how many parameters does eqn() take?
You didn't post it, so we can't tell you.

It's really a simple matter of making sure the declaration and the use agree with one another.

Please use the [code][/code] tags around the code to preserve the formatting and indentation.
