Whenever i try graphing absolute values or square rooting a number in home i get a missing error, does that mean i need to download it from somewhere and if yes, where?

and if not how do i fix it. I tried restoring it and everything and i've been so lost in class since my calculator keeps giving me this error.

Please help.

The missing error means that you did not close the parenthesis. When you use a square root or absolute value it always gives you the left parenthesis, (, but you need to close it with a right parenthesis, )

The quick way to determine absolute value is to square the value and take the square root of that.

So on the TI, with the value on-screen, just push these 2 keys in sequence (they are right next to each other):

x^2 squares the value (multiplies by itself), x^-1 inverts it (divides it into one), x! calculates the factorial, and square root calculates the square root.

I do not see why it would do that. Maybe you restricted the domain to positive values of the independent variable.

Anyway, my CX CAS has the latest OS version and it draws cube root for positive and negative values of x.

By the way the cube root is made up of one branch only, not 2 like the square root.

Here is a screen capture.

An *ERR: MEMORY* is given when there is not enough memory to
perform the instruction or function. To increase available memory by
deleting the contents of any variable (real or complex number, list,
matrix, Y= variable, program, Apps, AppVars, picture, graph database, or
string), follow these steps. • Press [2nd] [MEM] to display the MEMORY menu.

• Press 2: Mem Mgmt/Del.

• Select a variable or data that needs to be deleted and press [ENTER].

• Use the arrow keys to move the cursor next to the item, and then press [DEL]. The variable or data should now be deleted from the memory.

When deleting programs or Apps, a message asking for confirmation will appear. Select 2:Yes to continue. To leave any variable screen without deleting anything, press [2nd] [MODE].

• Press 2: Mem Mgmt/Del.

• Select a variable or data that needs to be deleted and press [ENTER].

Absolutely. The square-root function is the blue g-shifted function of the y^x key, 2nd row, leftmost column.

As an example, to calculate the square root of 5, press 5 g [square-root].

At first, **(-1)^(2/3)=1**. See captured image

For better understanding this problem noticed the graph of the function**y=x^(2/3)** below

It may be that you have somehow changed to a 'mode' that only shows integer values.

Try pressing the green button, then 5, then 9. Then try the calculation again.

If this fails, you can use Google as a calculator - search Google for sqrt(0.4053) and see what happens.. :-)

Use the toggle button above the enter key. It looks like 2 arrows

A circle is not a function and cannot be graphed in the regular y=screen. You can graph a circle in parametric mode.

To graph a circle in the regular y= screen, you have to graph it in 2 lines on the y= screen. I assume you've solved for y and gotten a square root equation. Remember a square root can be positive or negative. In line 1 of y= screen graph what you've been graphing and then graph the same equation in line 2 but with a negative in front of the equation. You'll get something that looks like an oval since the calculator screen is rectanglular. To make it look more circular (both parts aren't going to connect), press zoom and then select #5 (square).

If you would like to a root other than a square root, first enter the root value (3, 4, 5, etc.) then press MATH. Then Press 5 and enter the value you want to take that root of. Press ENTER.
