Question

g Write a function named distance that takes four parameters: the x- and y-coordinates of the first point, followed by the x- and y-coordinates of the second point. It should return the distance between those two points, using the Pythagorean Theorem, for which you will need to import the math module and use the math.sqrt() function.

Answer 1

Answer:

   static double distance(double p1x, double p1y, double p2x, double p2y){

       // distance = sqrt(x2-x1)^2+(y2-y1)^2

       double xcord = Math.pow((p2x-p1x),2);

       double ycord = Math.pow((p2y-p1y),2);

       double distance = Math.sqrt(xcord+ycord);

       return distance;

   }

Explanation:

• Using Java programming the language
• Create the function to accept four double parameters x1, x2, y1, y2
• Calculate the distance based on the formula $\sqrt{(x2-x1)^{2}+(y2-y1)^{2} }$
• Return the distance
