What is wrong with my variable ratio please help me.  I attached the Prime 3.1   file for you to correct my mistake   . I would like to make a graph like what I attached below. I appreciate your full support in advance  . Thank you.

Oh, and if you really want beta/epsilon on the horizontal axis. In Mathcad it can be done:

Don't know if this can be done in Prime...

You have an x as well as the ratio beta/epsilon. According to your documentation x=beta/epsilon.

Your functions should need a single parameter: x only. 

Then you get:

Note that there's an erro in the definition of K.L for the case A. The second condition should read X>=12.1 instead of x<= 12.1, because that situation is (partly) covered by the first condition. And the fact that K.L should be 1 when x<7 is not specified, but graphed.

I think you can complete your work now.

Success!

One more thing what is the shortcut of variable ratio in prime 3.1 ? I just copy and paste the b/e  in my other reference . CTR+Shift + k is not working in prime 3.1

I'm afraid it does not exist (yet) in Prime. Wonder if it will ever be supported.

Ah, one last thing.

Mathematically we did one thing wrong (I started, I'll take the blame): what happens in your function if x exactly equals 12.1. I think the second test should be "X>12.1".
