Re: Quadratic Inequalities

If you need help with it I will post a G program in the computer thread.


In mathematics, you don't understand things. You just get used to them.

Re: Quadratic Inequalities

Yes, I'd like that! I need the help because I'm only scratching around, not knowing where, what or how to scratch. I have to go to bed now, though. Catchya later...

Okay, when you get back there will be one in there. Have a good night.

Re: Quadratic Inequalities

G'mornin', Bobby. Off to work soon, but had time to correct my spreadsheet to incorporate the 'minimum' constraint I'd overlooked. Luckily it only took a few minutes as it needed just some simple tweaks.

I used conditional formatting to yellow-highlight equation-results cells that had values < -18, and also to identify those with value = -18.

Re: Quadratic Inequalities

As soon as I deal with dinner I will begin on the G work.
