I'm trying to use the Equation Writter in HP50G but I have a problem.
I cannot put a minus sign before a letter.
I cannot put sin(-x), it only lets me put sin(x).
Is this some obscure setting I don´t know?
How can I fix this?

It should work if you use the "+/-" key.
Let me know if it works.
Please remember to come back and let us know what did or didn't work
