How do you find "C" in terms of A, B, and θ? vectors...?
http://session.masteringphysics.com/prob...
If you have that problem in the picture, how could you find "C" (not vector C) in terms of A, B, and θ?
The other angle, φ, isn't included in the final answer.
Angle "c" is not in the final answer either.
I'm struggling with this and would appreciate help.
How do you find "C" in terms of A, B, and θ? vectors...?
Well, the only "C" I see besides the angle is the vector. But I assume that you mean that you just want the magnitude of C. In which case, you have, by the law of cosines:
C²=A²+B²-2AB cos c
Of course, c=180°-θ, and cos (180°-θ) = -cos θ, and magnitudes are always positive, so:
C=√(A²+B²+2AB cos θ)
The angle of C is of course (the angle of A) + φ.
Edit: You're welcome.

Regarding C++ !!! need Help?
Hi there, well i have downloaded microsoft visual c++ 2005 express edition. and whenever i write program it gives me error. ia m attaching my program and program and please somebody help me.
// unknown
//engr 30
//program 1
#include %26lt;iostream%26gt;
using namespace std;
int main()
{
cout%26lt;%26lt;"Welcome to Engineering 30!\n";
cout%26lt;%26lt;"Have a good day.";
return 0;
}
The error i get

Try starting your project as a "console" application as opposed to a windows application.
EDIT: which happens to uncheck the precompiled headers box automatically ;)
Reply:None of the other answers are correct. What you want to do, is in project properties, uncheck 'using precompiled header' because you are not using one. That is what stdafx.h is for.
Reply:there is no file called iostream in microsoft visual c++
so this error in coming......i suggest u that u first work on turbo c++ then switch to vc++ its will we good for knowing the language well
i hope it helped
Reply:At the risk of stating the obvious, have you tried the '#include "stdafx.h"' they suggest in your error message? It's been awhile since I've done some VC++ but I do recall needing stdafx.h or windows.h in almost all programs I built.

Dude.. send entire code and errors that the compiler throws up.
One error I can notice is usage of a[] Array size should be declared in definition itself; like you have done for c[10]
That style of declaration is allowed only in function calls.
Reply:1) const TAG_VALUE=1; // need a type like int!
2) c[]=a[]+b[];// no positions c[i] = a[i] + b[i];
3) cout%26lt;%26lt;"The MERGE_SORTED NUMBERS were:"%26lt;%26lt;c[]%26lt;%26lt;endl; // again missing the position.
and this might be 'while(f1)' probbably better to check for EOF, also whats with the ... never do that, its horrible.

Hey, please help me with some questions about C-Program!?
1) What are the header files in the C-Program?
2) What does "printf" do?
3) What does "scanf" do?
4) What are the data types in C-Languages?
This is for an assignment...
If possible, kindly include a site for my further info. Thanks a lot!
Hey, please help me with some questions about C-Program!?
1. header files are those files that hold the declarations of some of the functions and variables(and hence called "Pre-defined functions"). Those functions are put under different headers based on their function. Since those ".h" files are included usually at the top of a program file, they are referred to as "header files"
2. printf, a function under stdio.h(standard I/O header), prints a string- a raw string or values of variables - represented as format specifiers. it returns the total number of characters printed on to the standard console(Usually, the monitor)
3. scanf, a counterpart of printf, scans (or reads) values mentioned using format specifiers, from the stand console.(E.g. Key board). this too retrurns an integer, the total count of read characters.
4. Basic data types include:
int, char,float and double.
void can also be referred to as one of the data types.
Derived data types include:
Arrays, pointers and functions
"Let Us C" is widely acclaimed as the best guide for learning C.
Thank you,
Regards.
Reply:The headers file are files that contain prototype of many built in function in c program.
printf- is a function that allows u to display any kind of text in ur program.
the format is printf("your text");
as a result u'll get what ever u write in between the commas(in this case "your text") will be displayed in screen as u run the program.
But c program can't perform this function without a prototype(it tells c program how to perform). These prototypes are written in header files. So if u want to use printf function u will need to include the header files in ur program.
scanf- this function is used for take a input from ur keyboard and store it against a variable (u will have to define the variable name and data type first in ur program)
the format is scanf("%d", %26amp;name);
where name is the name of the variable and %d is a string that depends on the type of variable u are using.
data types are types of variables u can use on c program u will find details here

Why do ppl think HBCUs is something started b/c black ppl don't want to be included with white?
don't ppl know the only reason why they are called hbcu is b/c 50-60 years ago they were the only colleges accepting black students and other students of color?

Do nail technicians really make over $1000/wk b/c they get paid under the table(not including tips)??
I'm interested in learning how to become a manicurist/nail technician. Someone told me their salary per wk is %26gt;$1000 b/c they dont pay taxes. and is it true that they get insurance from medicaid even if they make that much $$ by just having a child in the household??
Do nail technicians really make over $1000/wk b/c they get paid under the table(not including tips)??
Doesnt sound true. If that were the case, i think alot more people would want to become a nail technician, dontcha think so?
And you are not gonna get medicaid if u did make $1000/wk. No matter if u have a child or not.
