### What is an dependent variable

All values that arise as influenced by changes in the values of other variable. Or, Dependent Variable is the observed factor.
If we have a Linear Function as
Y = mX + C
so,
Y should be Dependent Variable,
X as Independent Variable,
m as Coefficient and
C as Constant.

### I dont know what range is

At least two meanings.
In statistics ( say 1-var), let Xmin be the smallest value in the data set, and Xmax the largest value in the set.
Range= Xmax-Xmin

In functions and graphes
Let y=f(x) be a function, x is the independent variable and y the dependent variable.
The domain of the function is the set of all possible values that the independent variable can have: it is the pool where x takes it values, and the function f(x) its inputs.
The range of the function f(x) is the set of all possible values of the dependent variable, the set of all possible outputs of the function f(x)

### Can you initilise the value of a constant with the value of a variable

Whether or not you can do it depends on the programming language. In terms of best practice, it's usually frowned upon to initialize a constant using a variable.
The reason for this is that if it your value is truly a constant (e.g. pi) you'd know the value beforehand and would be able to hardcode it. Initializing a constant using a variable, implies that it's not constant and thus should be declared as a variable and not as a constant.

### TMESSAGE.TSF: GetLastError: 64 (40)

Hi there,

When do you get this message? Is it a home PC or office network?

Cause:

This problem occurs when the TEMP or the TMP environment variable has a space character in the folder name. For example, the following TEMP environment value may cause this problem: D:\Documents and Settings\UserName\Local Settings\Temp

Resolution:

To work around this problem, change the value for the TEMP or the TMP environment variable for the system account and for the user account that will be used to install SQL Server 2000 64-bit. If you want to restore the values for these variables after the installation, make a note of the values before you change them. To change the environment variable values, follow these steps:
1. Create a folder at the root of the local drive and name it TEMP.
2. Click Start, right-click My Computer, and then click Properties.
3. In the System Properties dialog box, click the Advanced tab.
4. Click Environment Variables.
5. Repeat the following steps for both the TEMP and the TMP User variables:
1. In the User variables list, select the TEMP variable, and then click Edit.
2. In the Variable value box, type %drive%\TEMP, and then click OK.

Note %drive% is the local drive where you created the folder in step 1.
3. Repeat steps a and b for the TMP variable, if it exists.
6. Repeat the following steps for both the TEMP and the TMP System variables:
1. In the System variables list, select the TEMP variable, and then click Edit.
2. In the Variable value box, type %drive%\TEMP, and then click OK.

Note %drive% is the local drive where you created the folder in step 1.
3. Repeat steps a and b for the TMP variable, if it exists.
7. Click OK two times to close the System Properties dialog box.
8. Click Start, click Run, type cmd in the Open box, and then click OK.
9. At the command prompt, type the following command to verify that the TEMP and the TMP environment values are equal to%drive%\TEMP:

set t

Note %drive% is the local drive where you created the folder in step 1.
10. At the command prompt, in the root of your SQL Server 2000 installation folder, type the following command: setup.exe /l*v C:\TEMP\setupfail.txt
Note If you want to restore the values for the TEMP and the TMP environment variables after the installation, follow step 2 through step 7 to restore the original values.

Hope this helps you.

### How do enter a lim of function when from one side using nderiv

Hello,
nDeriv( is valid only for real variables.
The syntax is as follows:
nDeriv ( expression, variable, value, epsilon)

expression: the function the derivative of which you want to calculate
variable: the name of the variable in the expression above (usually x)
value: the numerical value of the e x where you evaluate the derivative
epsilon: the numerical value of the tolerance. Default is 1x10^(-3). But you can change it to a smaller value to obtain a more precise result.

To use default value of epsilon
nDeriv ( expression, variable, value)

To use a different epsilon, ex 1x10^(-4)
nDeriv ( expression, variable, value, 0.0001)

nDeriv( A^3 , A, 5., 0.0001) should give you 75

Hope it helps.

### How to use the arc length function

Hello,
The arcLen() function is in fact a definite integral: You need the function, the name of the variable, the starting value of the variable, and the final value of the variable.

The syntax is as follows:

arcLen(expression1, variable, begining value, end value)

arcLen( f(x), x, a, b)
arcLen (cos(x), x, 0, pi) calculates the arc length of the cosine function from x=0 to x=pi

Hope it helps

In Actionscript 2.0 the output to the script below will be 15. Make sure that the values for the variables do not contain strings or extra characters like quotation marks. num1 = 5; num2 = 10; sum = num1 + num2; trace(sum);
