Question about Texas Instruments TI-89 Calculator

1 Answer

Doesn't operate as fast as it used to!

I used to solve some equations in the calculator that were a little bit confusing to solve by hand; it only took few seconds to do that. Now, it's taking more than 2 minutes or so to solve the exact same equations I used to solve before!! why is that? is there a way to take back to how it was?

Hello,
Put fresh batteries (main batteries)
Clear the RAM of junk variables and programs that clutter it" [2nd][MEM][F1][1:All memory]

Brush up on you calculator skills: shortcuts, command syntax for the commands you want to use; and start again. It might seem faster.
And no (The myth of the Paradise Lost has been with humanity since the beginings of time) if calculator has grown old there is not much you can do about it.

Hope it helps.

I am horrible at maths need help asap


With algebra you are learning problem solving-that is the process of problem solving using rules and equations. The best way to learn it is to shut out all distraction and work at it. If there is something you don't understand you may have to go back to the beginning and learn all the principals and rules that you don't understand- Algebra can be a very hard subject but it can be concord with persistence.

The circumference of a circle is 47.1 feet. What is the diameter of the circle?


The circumference of a circle is C=2 * pi * r or C= pi * d.

What do we know? C=47.1 and pi.

What are we trying to calculate? d

Put what we know in the equation and solve for d.

47.1 = pi * d

To isolate d, we have to divide both sides by pi.

47.1
------ = d
pi

I get 14.99' or approximately 15' as the diameter.

Good luck,
Paul
