Why it's "double" sqrt ?

Why there is Math.sqrt AND Math.pow ?? The formula is : (x2-x1)squared + (y2-y1)squared . So shouldn'e there be only math.pow ? Math.pow(x-x,2)+ Math.pow(y-y,2) ???

The last step of the Pythagoras theorem is the square root.

Check out what Google itself says or any of the pages it will show links to.

The formula is to get the square root(Math.Sqrt) of xDiffSquared(Math.Pow(X-x, 2)) + yDiffSquared(Math.Pow(Y-y, 2)) so you will need to use both. Hope this helps.
