Question about Texas Instruments TI-15 Explorer Calculator

3 Answers

Cannot get the "fix" to go off.

On the TI-15 I am having a problem getting the Fix function to go away. I inherited these calculators from a predecessor and they lost the manual so I'm trying to figure this out on my own and am afraid that I am going to mess it up even more. Thanks for any assistance you can provide. Angie Dubree

I am new to the TI-15 also, this one was dropped and was discarded as broken. Most equations returned a Zero, but the you could use the value in the next equation, so I knew it was there. The calculator displayed FIX OP1 OP2 and an up arrow in the left upper corner, I didn't know what any of that was for. My calc wouldn't reset but this did the trick. Press Mode, then down arrow three times. Arrow over to the Yes for a reset, then press Enter in the lower right. It will display MEM CLEARED and it should be good to go.

Push clear and on/off key at the same time. This is supposed to clear the operations on the calculator.

Not directly. The calculator does not have the trig functions built in. You could do it the same way people did it before pocket calculators.

Natural logarithm with TI-30XA calculator

I noticed that this calculator doesn't have a natural logarithm function as well. You can can always use the fact that
ln x = (log x) /log e or since log e is approximately .43429482
ln x = (log x)/.43429482. The greatest solution and it might be worth the 15 bucks or so to get a calculator with e^x and the natural logarithm function.
