dL/dt = k(1-L)

This is a logistic function, if I'm not mistaken.

It's a lab in my DE book. I need to find my personal k value. It's about rate of memorization.

It says I can use numerical methods or analytic methods. The problem is I don't know how to do either, apparently. I have my data, I just don't know how to apply it.

Any help?
