Graph plot oddity

[lrdheat]

In function app, I have functions in all 10 slots. I'm finding that, when simultaneously plotting functions, F7(X) will not plot if I have F6(X) & F5(X) plot, also F7(X) fails to plot if F4(X) & F5(X) plot. To be clear, F7(X) is not plotting for any case in which the above is a subset of the checked functions to plot

Could you copy/paste your formulas here? Everything seems to plot fine on my quick test.

How do I send this from the physical devise on my iPad?

F5 is -(x^2-1)/2 * (x-2) * (x+1)

F6 is -(x^2+1)/2 * (x-2) * (x+1)

F7 is -((x+1)^2)/2 * (x-1) * (x-2)

Hope you feel better soon!

as F5 is equal to F7, that's normal that asking to display both will only display one.

in CAS, type F5-F7, press Simplif... result is zero because F5 == F7.

Thanks!

That is great...I typed in the two functions, and did not recognize them as equivalent!
