write a java application that generate custemer account balance in a banking system?
An exception is literally that: an exception. Exceptions are thrown when something that shouldn't happen does. For example, if you're trying to turn "Hi" into an Integer, you'll get a NumberFormatException (in Java.) If there is nothing in place to handle an exception, the program will crash. Try-catch blocks are used for exception handling within methods, and exception throwing is used to give out exceptions, or let a different method handle it. Example program (Java): class ex{ public static void main(String[] args){ String Strx = "5a"; int x = 0; try{ x += Integer.parseInt(Strx); }catch(NumberFormatException e){ // If Strx is not an Integer x += Integer.parseInt("5"); } System.out.println("The value of x is " + x); // The value of x is 5 } } Alternatively, you could remove the try-catch blocks, and simply write "public static void main(String[] args) throws NumberFormatException" in the 2nd line of the program.
In practice, it is better to use the Math class, which already has a pow() (i.e., power) function. If you want to program it yourself, just write a loop:double myPower(double x, int y){double result = 1;for (int i = 1; i
The exclamation equals in Java(x!=) is used to represent the logical NOT.
integral of e to the power -x is -e to the power -x
The first derivative of e to the x power is e to the power of x.
The power law of indices says: (x^a)^b = x^(ab) = x^(ba) = (x^b)^a → e^(2x) = (e^x)² but e^x = 2 → e^(2x) = (e^x)² = 2² = 4
e^x/1-e^x
d/dx (e-x) = -e-x
f(x) = (x^2)(e^x)f'(x) = e^x((x^2)+2x) - i thinkf"(x) = ?--------f(x) = (x^2)(e^x)apply the power rulef'(x) = (x^2)(e^x) + (2x)(e^x)apply the power rule to the first part and apply the power rule to the second part, then add those togetherf''(x) = [(x^2)(e^x) + (2x)(e^x)] + [(2x)(e^x) + (2)(e^x)]simplifyf''(x) = (e^x)(x^2 + 4x +2)I got it right. It checked out on my calculator.
e^(3lnx)=e^[ln(x^3)]=x^3
No, its Volts x current = power. To be correct its W = I x E where watts = power, I = amps or current and E = electromotive force or voltage.
Mac OS X has Java already installed. You do not need to download it and install it currently, and Java apps should have no problem running. It has to be a real java app, not a Windows exe file compiled that also uses java, that is still a Windows program. When Mac OS X 10.7 comes out, it will not have Java installed by default, and you have to install it manually just like you do on Windows.... just download the Mac version and install.

if you mean e to the x power times log of x, it is e to the x divided by x
e^(-2x) * -2 The derivative of e^F(x) is e^F(x) times the derivative of F(x)
