Java Program in JAVA which simulates the solar system

Click For Summary
To simulate the solar system in Java using Beeman's algorithm, it's essential to understand how to decompose vectors into their x and y components. Vectors can be represented in rectangular or polar form. If the vectors are in rectangular form, the x and y components are directly available. For vectors in polar form, which consist of a magnitude and an angle, trigonometric functions can be used to calculate the x and y components. This foundational knowledge is crucial for implementing the simulation accurately.

Hi
I need to write a program in JAVA which simulates the solar system. I'll be using the Beeman's algorithm seen here: http://en.wikipedia.org/wiki/Beeman%27s_algorithm"

My question is that if I have the vectors for : velocity, acceleration and position how do I decompose them into there x and y components? I have forgotten a lot about the basics of vectors.

Please help
thanks

srose:
Vectors are expressed in rectangular form or polar form for the 2-D variety. Which do you have? In the rectangular form, the x and y components are given. In polar form, where a magnitude and an angle are given, simple trigonometry produces the x an y components.
