How can you graph equations (functions) if you do not have a graphing calculator?

Unfortunately, the TI-30Xa calculator does not handle algebraic expressions.

If you are interested in knowing more about the capabilities of the calculator, follow the link to download the guide book.

You don't want the square root. In this example, you want the sixth root.

Press 4 5 2nd [xth-root] 6 =

The xth-root is the shifted function of the y^x key, located just above the divide key.

This calculator cannot solve equations and does not have an x key. You will require a calculator with a computer algebra system like the TI-89 or TI-nSpire CAS.

The TI-30XA does not offer any symbolic algebra or equation solving functions. You will need to do some work on paper. However, its not super difficult.

Solving quadratic equations (finding the roots) involve three steps:

You should exercise this simplification with different examples until you can do it in your sleep. The goal is to get a form x² + px + q = 0, where in the above example case, p = -1 and q = -2.

Now, use the memory places #0 and #1 to store p and q, as in:

-1 [STO] 0

-2 [STO] 1

Next, you should determine the discriminant D = p² - 4q of the equation using your TI-30XA calculator. Having put the two values into the memory comes in handy here:

[RCL] 0 [x²] [-] 4 [x] [RCL] 1 [=] [STO] 2

Note, we put D into memory place #2, we will need it again later.

Now check the displayed value D:

and you'll receive the original, normalized equation.

As an exercise for your understanding: you can save a few keystrokes by saving -p to memory #0 instead of p. Try to figure out why this helps.

Solving quadratic equations (finding the roots) involve three steps:

- Simplify the equation and bring into the normalized form x² + px + q = 0.
- Determine the discriminant D = p² - 4q and check if there are two, one or no solutions at all.
- Calculate the root(s), if any.

- if D
- if D = 0, there is exactly one solution: -p / 2. Key in [RCL] 0 [+=-] [÷] 2 [=] and the displayed value is the only solution to the quadratic equation.
- if D > 0, there are exactly two solutions:

Key in [RCL] 0 [+=-] [+] [RCL] 2 [] [=] [÷] 2 [=] to get the first root, and

[RCL] 0 [+=-] [-] [RCL] 2 [] [=] [÷] 2 [=] for the second root.

and you'll receive the original, normalized equation.

e^x is the 2nd function of the LN key, second from the right on the top row of the keyboard.

I have a few questions and then I should be able to help you. In the equation you want to solve there is a letter g. Is this supposed to be there? Does this represent units such as grams? If this is the only units in this equation the answer will be mass not volume. Lets ignore the units and just punch in the numbers. Assuming the equation you want to solve is 3.70/2.50 x 10^-6. The buttons you need to push are 3.7/2.5 EE 6 [+/-] =. The EE button is the exponent button and the [+/-] button is the change sign button, located just below the 3. The change sign button changes the sign of the proceeding character, in this case it changes the 6 into a -6. This calculator will calculate the exponents before it does the multiplication or division so you don't need to use any parentheses for this equation. I hope this helps you out.

well I`am having a promblem with fractins and its hard for me to divid a fration

The TI-30XA cannot solve algebraic equations. You need a more advanced calculator for that, like the TI-89.
