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.

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.

A quantity that can vary independently on any other quantity in the situation being studied. When a independent variable changes it value, the value of the dependent variable changes in accordance with the rule that links the two variables. As a worker, you can decide of your own free will to work 10 hours or 40 hours per week (the number of hours worked is the independent variable). Depending on the course of action you choose (10 or 40, or 0 hours), your weekly salary will vary according to the pay-formula.

weekly salary =(number of hours worked in the week)* (hourly rate)+ some constant.

weekly salary =(number of hours worked in the week)* (hourly rate)+ some constant.

Sorry to be the bearer of bad news, but the HP 10S calculator does not perform matrix calculations.

You have 9 variables A to F, M, X and Y. You can use them to store data, constants, calculation results, and other numerical values.

To store say the value 5674 in Variable A you press the key sequence 5 6 7 4 [SHIFT] [STO] A.

To recall the value stored in A (and use it in another calculation) you press [ALPHA] [A]. It will be displayed and you can do with it any calculation you want.

You can enter (store) data in Statistics modes

- Mode 2 is for standard deviation SD (1-variable statistics)
- Mode 3 is for Regressions.

No need for a claculator to understand these concepts.

A linear function is a function of the form y=ax+b. It contains an independent variable,x, a dependent variable, y, and two constants, a and b,

The value of the constant a is the measure of the rate of change of the function, The value of the constant b is the ordinate (value along the y-axis) where the straight line cuts the y-axis. It is called the y-intercept, or the initial value.

If the value of b=0, the straight line passes through the origin O(0,0). The purists call this type of variation, a direct variation. If b is not equal to 0, it is called a partial variation or some other name.

If you have the graph drawn, b is read off the y-axis: You look at the graph and try to estimate the ordinate of the point where the line cuts (intersects) the y-axis.

To get the rate of change a, you select two points on the line. Let 1st point have coordinates (x1,y1) and the 2nd point have coordinates (x2,y2).

The rate of change is given by the ratio (y2-y1)/(x2-x1). You can also use a= (y1-y2)/(x1-x2). Respect the order in the two expression or you will get the negative value of the rate of change.

The memory locations A,B,C,D,X,Y and M are available to store values in them. M is the constant memory.

To type the name of, say, variable X, you press the ALPHA key then the the key next to which is the X in cyan/Green color. If I remember correctly it is the key marked with a parenthesis ).

However to store a value in a memory location or to recall a stored value you use the STO key to store and the RCL key to recall. To store or recall there is no need to press the ALPHA key.

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.

If all values for a specific "dummy" variable are identical, then you should delete the variable, because it adds NO information to your analysis.

If all values for one "dummy" variable MATCH the values for another "dummy" variable, then the two variables are 100% correlated -- remove one of them from your analysis.
