processing: How can make a function that's finding me the results of an quadratic formula with an array?

-1

I have an assignment to do and have no clue how to do it.

given is a quadratic equation:

y = a*x*x + b*x + c

thats my code so far:

void setup(){

    println(quadratic(4, 6, 1));

}



float quadratic(float a, float b, float c){

    return (-b + sqrt( b*b - 4*a*c)) / (2*a);

}

I have to write an function that's giving me the coefficients as parameters and the results as an array.

I just don't know how to make an array.

thank you so much in advance!

It's really hard to help with general "how do I do this" type questions. You're going to have to break your problem down into smaller steps and approach those steps one at a time. Then if you get stuck, post a Minimal, Complete, and Verifiable example along with a more specific question. Good luck.

Looks like you need to encode the quadratic formula into Java.

I'd recommend googling something like "Processing array" or "Java array" for a ton of results.

The Processing reference is a great first place to start. Here is the reference for arrays in Processing, and it includes sample code like this:

int numbers = new int[3];

numbers[0] = 90;  // Assign value to first element in the array

numbers[1] = 150; // Assign value to second element in the array

numbers[2] = 30;  // Assign value to third element in the array

int a = numbers[0] + numbers[1]; // Sets variable 'a' to 240

int b = numbers[1] + numbers[2]; // Sets variable 'b' to 180

Shameless self-promotion: here is a tutorial on arrays in Processing.

@nilezguy Which part is giving you trouble? Start with something simpler. Create an array using hard-coded values. Get that working first, then try to add in more logic. Then if you get stuck, you can post a Minimal, Complete, and Verifiable example along with a more specific technical question. Good luck.
