# Abs( and square roots

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.

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, )

### Anyone know how I can do Absolute Value on this?

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):

### What is x2,x/1,x! andsquare root symbol means and their value?

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.

### How to use square root for non square numbers for casio graphing calculator

You can use the square-root function for any number, whether it's a perfect square or not. For example, to calculate the square root of 2, press SHIFT [square-root] 2 EXE .

[square-root] is on the x^2 key, just to the right of the ALPHA key.

### Why does the TI-nspire not give complete graphs of cube root and other franctional power functions?

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.

### Everytime I try to do powers and square roots I get an error message

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].

### Can I use the HP 12c to figure out square roots of numbers

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].

### The calculator is only graphing a half circle when it should be a full circle, specifically not in the negative y-values of the plane.

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).

### I need to use the square root sign but I need to square root with 3, 4, and so on.

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.
