[Help] Program to solve resultant vectors?

Program to solve resultant vectors?

I would like someone to help me if they could. Where to start. I wanna make a program that automatically solves resultant vectors.
How to solve resultant vectors:

Formulas:
X = MCosΘ
Y = MSinΘ
M = √X²+Y²
Θ = Tan^-1(Y/X)

To start we need to find the X,and Y components of the first vector...
Let's says the magnitude of the first vector is 120m. and the Degrees is 15°.
and the magnitude of the second vector is 132m and the degrees is 20°.
We need to do 120Cos15° + 132Cos20° to get the X component of the resultant vector.
Next we do 120Sin15° + 132Sin20° to get the Y component of the resultant vector.
Now we need to find the magnitude of the vector so we use the m = √X^2+Y^2 formula which gives us the magnitude.
Now we need to find the direction (degrees) which is the ArcTan formula.

Any ideas on were to start?

Sounds more like a homework, and why 2 threads?

You already said everything you need to do... Just translate it to code...

That's how to figure it out. I don't know where to start with the code. Like how to make the program do the math? I'm not so experience with visual basics. That's why i am asking for help.

Sorry Brinuz i accidently posted twice.

All you basically do is rewrite the problems in vb.net

Such as,

A + B + C = D

Code:

Dim A, B, C, D as Double
D = (A + B + C)

Create 2 magnitude variables
Create 2 degree variables
Create 2 component variables
create resultant magnitude variable
create resultant direction variable

Find the X component of the resultant vector
Find the Y component of the resultant vector
Find the magnitude
find the direction

some pseudo code

Code:

dim magX, magY, angleX, angleY, resultantX, resultantY, resultantMag, resultantDeg as double

resultantX = (magX * cos(angleX)) + (magY * cos(angleY))
resultantY = (magX * sin(angleX)) + (magY * sin(angleY))

resultantMag = sqrt( (pow(resultantX,2) + pow(resultantY,2) )

resultantDeg = atan( (resultantX / resultantY) )

By 'pseudocode' you mean C/++, with VB variable declarations? Lawl.

it's not C/++ because there are no semicolons

what if I wanted to practice declaring variables in vb?

For the math functions:
