Vector Calculator Version 1.0 Read.me September 9, 1989

As I participated in my University Physics class, I found

that most of the time, as I did problems involving vectors, the

incorrect solutions I got were usually not from a misuse of

concepts, but from punching in the wrong numbers on my

calculator. The repetitive calculations were a great source of

error, not to mention a time waster!

After doing a cursory check in computer magazines and

checking bulletin boards, I discovered no available programs to

do simple vector algebra.

Taking C compiler in hand, I set out to write a program to

do straight forward vector algebra with little fuss or fluff.

Vector Calculator 1.0 is the result.

The program accepts commands through the function keys,

immediately calculating all values upon receiving vector

parameters.

Program Commands:

F1 = Vector 1 components.

Press the F1 key to enter the X and Y components of Vector

1. The computer will blank the current entry in the X component

field and place the cursor in the field. Type the X component

value. Press enter when you finish. The cursor will then be

moved to the blanked Y component field. Type the desired value

in, terminating with the enter key. After entering the

components, the magnitude and angle in degrees and radians for

the new vector will be calculated and updated to the screen. The

sum, dot product and cross product will also be calculated and

updated.

F2 = Vector 1 Magnitude.

Press the F2 key to enter Vector 1 by magnitude and angle in

degrees or radians. The cursor will first move to the magnitude

field. Enter the value. Then the cursor will move to either the

degree or radian field depending upon the degree/radian toggle

setting (see F9). After entering the angle, the vector

components will be calculated and updated along with all other

calculated values.

F3 = Vector 2 components.

Press the F3 key to enter the components of Vector 2 as

described above in F1.

F4 = Vector 2 magnitude.

Press the F4 key to enter the magnitude and angle of Vector

2 as shown above in F2.

F5 = Swap sum to 2.

Press the F5 key to cause the values currently displayed as

1

the Sum to be entered as Vector 2. This function is very useful

when finding the sum or products of more than two vectors. For

example: When finding the sum of vectors A, B and C, first enter

A as Vector 1, then enter B as Vector 2. The Sum now shown is

the vector sum of A and B. Press F5. The sum of A and B is now

entered as Vector 2. Enter C as Vector 1. Now the Sum shows the

vector sum of A and B (as Vector 2) and C.

F8 = Clear all.

Press the F8 key to clear all current values to zero.

F9 = Toggle to radians/degrees.

Press the F9 key to toggle the degree/radian input setting.

When entering vectors by magnitude and angle, the angle measure

can be in either degrees or radians. This toggle will allow you

to choose which unit will be entered when using commands F2 or

F4. When the program first starts, the command on screen will

read "Toggle to radians." This means that the program currently

will accept angle measures in DEGREES. If you wish to enter

angles in radians, press F9. After pressing F9 the display will

read "Toggle to degrees" and will accept angles in RADIANS. You

need not enter all vectors in only degrees or radians, as you can

toggle the setting without effecting the current calculations.

For example, if you must sum two vectors, A and B, given by

magnitude and angle. The angle for A is in degrees and B is in

radians. Press F2 and enter the magnitude of A and the degree

angle of A. Press F9 to toggle to radians. Press F4 to enter

the magnitude of B and the radian angle of B. You now have your

sum in radians or degrees.

F10 = EXIT

Press the F10 key to exit from the program to DOS.

This program is not what I would call "polished" or

finished. I already have many ideas for improvement and

additional functionality.

If you find this program useful or have any suggestions,

criticisms, or comments (even praise maybe) please contact me by

mail. My address is:

If I receive enough good ideas the new version will come

sooner, as I allot my spare time to the most productive or

requested tasks.

Enjoy!
