Change NORMALD_CDF([mu,sigma,]x) into NORMALD_CDF([mu,sigma,]x,[x 2])

[vanveen]

I am teaching with the HP prime calculator. 2 of my students do not hat the option to enter a second border in the formula NORMALD_CDF.

The help key results in sintaxis NORMALD_CDF([mu,sigma,]x)

And the other students have in the help syntaxis NORMALD_CDF([mu,sigma,]x,[x2])

How do i change this, so the first two atudents have the option of a second border?

Those student just need to update the calculator. They are out of date by approximately 2 years I think (from memory). Then it will have it like the others.

Prime is more like a modern smartphone - including that we are always adding new features and improvments based on user feedback. It will always be a good idea to update them at the start of class or more regularly then with old historic calculator models.
