The basic question is Is there a script to fix my calculator from squaring negatives and giving me a negative in return.
HOW on the calculator (I presume) did people get the distance of w sub 1. I use the distance formula with w sub 1, but it says non real answer. I assume it does this because of its priorities when calculating square roots. I try to fix the issue by changing the numbers to positives, because when they are squared, it should give the same number, yes? Well, I don’t get the right answer, I get a redundant answer which doesn’t help me in the slightest bit. I skip it for the moment and go onto w sub 2. I realize ONE of the numbers in w sub 2 is negative before I punch them in so I take note of that. I use the distance formula on w sub 2 and it works fine. I found this strange as the calculator was NOT ok with me putting both numbers as negative in. I try to test something (since I got the incorrect “redundant” answer on w sub 1) by doing the distance formula for w sub 2 again, except this time, I change the negative number to a positive. In theory this would give me the exact same answer as when it was negative.
The square root of -3^2 should give 9 and positive 3^2 would also give 9, yes?
Well, it ended up giving a bogus answer that made no sense at all. ( I was using the practice problem for this theory, as I knew the correct answers)
I tried one simple test just to see if my calculator was acting as stupid as I thought.
I punch in negative 3 squared. It gives me negative 9.
So I think back to what I had begun with and thought to myself, how in the world did all the other people who got w sub 1’s distance get it? I know the issue with the squaring of negative is not limited to my calculator, as a friend noticed the same problem with his and it was a different model.
I believe the next test or two is to see whether other calculators of the same model have this issue and whether somebody has a script I can use to fix this.
