Calculators Integrating with Constant Variables: TI-89 Symbolic Integration

[cscott]

How can I integrate an expression with constant variables like needed when solving m\frac{dv}{dt} = mg 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... \int kx \cdot dx gave kx \cdot x

 

[dav2008]

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

Ohh, thanks!
