##Example Usage

import 'package:dart_math/algebra.dart';
import 'package:dart_math/dart_math.dart';

main(List<String> arguments) {
  //Intantiate a Fraction Object
  Fraction fractions = new Fraction(3.0, 2.0);
  Fraction fractions1 = new Fraction(5.0, 4.0);
  Fraction fractions2 = new Fraction(5.0, 2.0);
  Fraction sumfrac = fractions.fracAdd(fractions1).fracAdd(fractions2);

//get nominator,denominator, quotient,remainder;
  print(
      'Nominator: ${sumfrac.nominator()} Denominator ${sumfrac.denominator()}');
  print('This is quotient ${sumfrac.quotient()}');
  print('This is remainder ${sumfrac.remainder()}');

  // //Intantiate Line Object
  Line l1 = new Line(y: 1.0, gradient: 2.0, intercept: 3.0);
  Line l2 = new Line(y: 1.0, gradient: -0.5, intercept: 7.0);
  Line l3 = new Line(y: 1.0, gradient: 2.0, x: 1.0);

//Intanciate Cordinates Object
  Cordinates p1 = new Cordinates(x: 1.0, y: 1.0);
  Cordinates p2 = new Cordinates(x: 2.0, y: 3.0);

  print('This is distance ${p1.getdistance(p2)}');
  print('This is Slope ${p1.getslope(p2).getGradient()}');
  print('This is y intercept ${l3.findYintercept()}');

  Cordinates inter;
  Map<String, double> cord;
  //get intersection of two lines
  inter = l1.intersection(l2);
  print(l1.intersection(l2).toLine(p1));
  cord = inter.getcordinates();
  print('These Lines intersect at $cord');

  //Startof Algebra
  Quadratic quadratic = new Quadratic(2.0, -1.0, -1.0);
  print(quadratic.discriminant());
  print(quadratic.roots());

  Line l = new Line(gradient: 2.0, intercept: 2.0, x: 3.0);
  Cordinates c = Cordinates(x: 3.0);
  print('Get y value given X ${c.findY(l).getcordinates()}');

//point of intersection between circle and Line
  Circle c1 = new Circle(
      new Cordinates(x: 2.0, y: -3.0), new Cordinates(x: 2.0, y: 3.0), 2.0);
  c1.lineIntersection(Line(
    gradient: -1.0,
    intercept: -0.5,
  ));

  c1.radius();
