    How can I integrate an expression with constant variables like needed when solving [itex]m\frac{dv}{dt} = mg[/itex] but assuming I don't know its value?

    Just type any constants in as letters. (Make sure you don't have any values stored to those letters first)

    I don't think it's working... [itex]\int kx \cdot dx[/itex] gave [itex]kx \cdot x[/itex]

    Make sure you type in k*x instead of just kx. It thinks that "kx" is one variable if you don't.
