New user of the HP Prime calculator. I'm running into several problems that I haven't found answers to in the User Guide or elsewhere, so any help would be greatly appreciated!
When I enter a derivative in either normal mode or CAS mode, like diff(x^2*(15/6x)-x,x it's just returned in the form of the product rule, but I expect the calculator to return the derivative, 5/2 – 3x^2. How do I get the calculator to finish deriving it?
When I enter an implicit derivative: implicit_diff(xy) or implicit_diff(xy,x,y) it returns either "Error: Syntax Error" or "Error: Bad Argument," with no further explanation. What am I doing wrong?
Is there a quicker way to access diff() and implicit_diff() than scrolling/searching the catalog?
I get the "Error: Syntax Error" a lot. How can I find out what I'm doing wrong in each instance? The built-in Help function doesn't help.
When I enter a derivative, the calculator echos it as (expression)' with a tick indicating it's taking the derivative, but it won't allow me to use this syntax when entering a derivative, which would be much faster than via the catalog.
