import java.util.ArrayList;
import java.util.Arrays;
import java.util.Collections;

public class Arvutused {
static ArrayList listx = new ArrayList();
static ArrayList listy = new ArrayList();

public Arvutused() {

double x, y, t = 10.0, samm = 0.1;

while (t >= -10.0) {

t = t - samm;

x = xValue(t);

y = yValue(t);

listx.add(new Double(x));
listy.add(new Double(y));
