A question is asking me to double integrate cos(3x+4y)dA over R=[2,6] x [2,5]

How do I interpret [2,6] x [2,5] ??

Why does 1+ [1/2((e^x)-(e^-x))]^2 equal [1/2((e^x)+(e^-x))]^2 ???

i know my friend's user name, but i can't find her channel and i want to share videos with her!

Dim SourceRange As Range, DestRange As Range

Dim DestSheet As Worksheet, Lr As Long

Dim Number

Dim ccfid As String

With Application

.ScreenUpdating = False

.EnableEvents = False

End With

'fill in the Source Sheet and range

Set SourceRange = Sheets("Verify").Range("A69:J69")

Number = Sheets("Verify").Range("F11")

ccfid = Sheets("Verify").Range("F7")

Dim length As Integer

length = ccfid.length

If length < 8 Then

GoTo IDError

ElseIf length > 8 Then

GoTo IDError

Else: GoTo NoErrors

End If

above is a snippet of my code.

i'm getting the error on the line length=ccfid.length

i'm using microsoft excel 2000

I want to write an Excel worksheet that when you open it, the first thing that happens is a popup window that asks the user to enter data into 3 or 4 fields. How would I do this?

I just finished creating a game and i wanted to create a batch file to run it with a simple double-click. I saved the game's runner file as .bat, but when i clicked on the icon, command prompt popped up, gave a bunch of errors and then closed automatically.

I know that my game works because i can run it from the java file. Why won't this work?

I have a picture that I want to convert into a BufferedImage so that I can check the colors of each individual pixel. How should I go about doing this in Java?

The object of the game is to have only one peg left standing.

You can move pegs only by jumping over other pegs and when you jump over a peg, it is removed from the board.

My computer has Yahoo Parental Controls on it and it keeps track of every website I visit. However, if I use a proxy, will the proxy's website be logged?

I am an officer in the MUN club of my school and would like to know if anybody knows about any upcoming conferences in the Northeast United States that host high school teams?!?1

I know that System.out.print("\n") makes a new line... \t does a tab..

are there any other \+character combos that do cool things? i know \7 makes the system beep! what does \b do? are there any more? list as many as you know that work.. whoever has the most gets best answer!

I'm very interested in international affairs and all that but when this conflict started, i was on a plane back from india so i really didn't catch what started the whole conflict!

my assignment was to make these two designs using the first initial of the user:

*****

****

***

**

*

and the second shape is a reflection of this over the y-axis, like below but without the -'s:

*****

-****

--***

---**

----*

my code for the first one was this:

{

int a=0;

System.out.print("Enter your first initial: ");

String shape2;

shape2= reader.next();

for (a=5;a>=1;a--)

{

for (int b=a;b>=1;b--)

{

System.out.print(shape2);

}

System.out.println();

}

}

how can i alter it to make the second pattern?

Ok, here's the thing.

I have a String that I named "grade"...without the quotes.

I'm making a while statement and i want it to only work while grade is not equal to "Z" or "z"

I know that if I wanted the while statements to run if it WAS equal to "z" or "Z" I would write:

while (grade.equals("Z")||grade.equals.("z")){

statements are here

}

but i don't how to do it the other way.

can you help?

import java.util.Scanner;

public class Krishna_Quadratic {

public static void main(String[] args) {

double a;

double b;

double c;

Scanner quad=new Scanner (System.in);

System.out.print("Enter the value for 'a': ");

a= quad.nextDouble();

System.out.print("Enter the value for 'b': ");

b= quad.nextDouble();

System.out.print("Enter the value for 'c': ");

c= quad.nextDouble();

double x1;

double x2;

double discrim;

discrim= Math.sqrt(b*b-4*a*c);

x1= (-b+discrim)/2*a;

x2= (-b-discrim)/2*a;

System.out.print("The values of 'x' are " + x1 + "and " + x2);

}

}

That's my code but I don't know how to deal with the square roots of negative numbers. How do I tell the program to display that instead of NaN?
