Hi there,

Save hours of searching online or wasting money on unnecessary repairs by talking to a 6YA Expert who can help you resolve this issue over the phone in a minute or two.

Best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

Here's a link to this great service

Good luck!

To evaluate the expression you need the value of x.

To solve you do as follows

ln(5x)=12/4=3

Take the exponential of both sides of ln(5x)=3

e^(ln(5x))=5x=e^(3)

This gives**x=(1/5) e^(3)**

To solve you do as follows

ln(5x)=12/4=3

Take the exponential of both sides of ln(5x)=3

e^(ln(5x))=5x=e^(3)

This gives

Did you find a solution for this ?

You haven't received any help because the request looks a lot like a homework assignment and a lot of people are unwilling to do that.

I have some suggestions:

1) You should make sure that you have a working copy of Java. Start at the Java Tutorial: http://docs.oracle.com/javase/tutorial/java/TOC.html

If you do not have a working Java on your machine, follow the link at the top right of that screen to 'Download JDK'. That is the set of programming tools you need to use to compile and run programs.

The Installation Instructions will tell you everything you wish to know. I suggest that you use: http://notepad-plus-plus.org/ to type in programs.

Good luck. Post more on the problem page for more help.

This calculator cannot do algebra ( manipulating expressions with letter symbols) . It does not have a CAS (computer Algebra System). All it can do is evaluate (find the numerical value of) expressions typed in. If it has the appropriate keys to enter variables such as A,B,C, or X and Y., and you entered an expression with variables it will use the numerical values stored in the variables. If you have not stored anything in a variable, it is given the value 0 by default.

The calculator does not have a CAS (Computer Algebra System). Therefore it cannot do symbolic algebra. It can only calculate numerical values.

You can enter algebraic expressions with symbols (X, variable), Y, A,B,C,D, and M but they will just be evaluated with the current values of A, B,C,D, Y, and M. If you use the SOLV program the unknown variable must be X.

In order to understand the difference between high-level programming languages and lower level languages you might have to have a deeper knowledge of computers than you currently have, although I can try to the best of my ability to explain it simply.

Lower level programming languages are more directly related to the actual machine language that the computer ends up reading in the end. Higher level programming languages are less representative of the actual machine code, and as a result may require either a more advanced compiler or may require being compiled several times. Generally higher-level programming languages are easier for the user to write in than lower-level languages.

If you want to get an answer like 1/2X for d/dx(X^2), you will have to
purchase a CAS calculator like Casio's Algebra FX-2 or Classpad. TI series calculators also have CAS.

However, you can calculate the numerical values of derivatives and integrals only.

To calculate the value of a proper integral:

**∫**xdx from 0 to 2, input as follows:

**∫**dx(X,0,2)

To calculate derivative at a point:

SHIFT+**∫**dx key X^2,3)

Display looks like this: d/dx(X^2,3).

However, you can calculate the numerical values of derivatives and integrals only.

To calculate the value of a proper integral:

- Press the 'ON' key;
- Press the Integral key ;
- Enter your expression (example X^2+X-3 etc);
- Press the 'comma' key after your expression;
- Input the first limit after comma, input comma again after first limit;
- Close brackets;
- Press the equals key, display may return after a while with the answer.

To calculate derivative at a point:

- Press Shift and then the integration key.
- Enter your function;
- Input comma;
- input the point at which you want to evaluate the derivative;
- Close bracket and press enter.

SHIFT+

Display looks like this: d/dx(X^2,3).

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.

This code takes two arguments, a string constructor from the Java language and an integer. Its purpose is to parse (meaning de-construct or disassemble into component parts) one data type into another.

Here is an example of a Java program to specify and print out the dimensions of a rectangle, taken from the page http://www.roseindia.net/java/beginners/entervaluesfromkeyboard.shtml:

length = x;

breadth = y;

}

}

}

Rectangle rectangle =

rectangle.show(a, b);

System.out.println(" you have entered these values : " + a + " and " + b);

System.out.println(" area of a rectange is : " + area);

}

}

After you add the new record into table A, you can use the
LAST_INSERT_ID() function to retrieve the value of the auto_increment
PK field. Look here for more information on this function: http://dev.mysql.com/doc/refman/5.0/en/information-functions.html

The main cause of this error is you havent set the environment variables correctly, you can do it as follows

Right click on "My Computers" select properties the click "Environment variables" then under "User variables for pcname"

select new and add the following paths

1)var name:path

var value:C:\Java\jdk1.5\bin

2)var name:classpath

var value:C:\YourJavaCodeDirName

click ok and its done
