programing the t-84 can you help?

Question

Having a mid term soon and the professor said that some caculators can be programmed for the quadratic equation.

He said if you can put it in yours, you can use it. I am sure my caculator has the capability, but not sure how to get a minimum and maximum. Can you help?

Answer 1

The first step would be to ask your classmates (or people who have already taken that or a smiliar class) if they have this already stored on their calculator. It is likely several do. You can transfer between calculators using the cable you got when you bought the calculator. If that's unsuccessful, do a search for "TI-84 programs" on your favorite internet search engine (such as Google). You'll find literally thousands of results, and in most cases you can transfer the programs to your calculator via a USB connection.

Failing both of those, you still have other options.
A. If you find the quadratic formula hard to remember, you can store it as a text string on your calculator. Begin and end what you want to store with quotation marks (ALPHA, +), and when you're done, hit the STO► key and a letter where you want to store it (like "Q" for "Quadratic"). You can store any number of things in your calculator this way, and many of your classmates probably do cheat that way--though it's actually more common in science classes than math classes.

B. You can find the real (but not complex) roots of a quadratic function by graphing. Make sure the equation is in the form Ax^2+Bx+C=0. Then go to Y= on your calculator and enter the function (everything but =0) on the first line. If you can't see anything on the screen after graphing, hit ZOOM, and scroll down to the line that says "ZoomFit", and press ENTER to show the graph. Once you can see the graph, hit "2nd" and the TRACE key to get to the CALC menu. Select Zero. The calculator will ask for lower and upper bounds. Use the arrow keys to move the cursor to the left and right of a place where the graph crosses the x-axis (which is what an answer to a quadratic equation means). Hit ENTER two more times to get the answer. (Then repeat to find the other root.)

Answer 2

There are a few programs available for the TI-84 that can be used for solving the quadratic equation. I would go to ticalc.org, and look for a program there. The link below is directly to the list of math programs, and if you search that page for the quadratic equation you'll come up with quite a few results.

Answer 3

this does not artwork because the structure of your pc (in all likelihood Intel x86 nicely matched) is incompatible with the processor contained in the TI-80 4 (Z80). It seems that you'll actual get assembler or perhaps C compilers for the Z80 although which will artwork on your pc, even although you won't be able to attempt them very genuinely. obviously the sending area is trivial.
