Not a problem if youve watched this tutorial. We can just look for the point of intersection between y 3x 2 and the line that is perpendicular to y 3x 2 and passing through 5 1 The line that is perpendicular to y 3x 2 is given by y -13x b. Derivation of the Distance Formula.
We can either convert the polar points to rectangular points then use a simpler distance formula or we can skip the conversion to rectangular coordinates but use a more complicated distance formula.
Walk through deriving a general formula for the distance between two points. Consider a point P in the Cartesian plane having the coordinates x 1y 1. Next connect points A and B to reveal a right triangle. Walk through writing a general formula for the midpoint between two points.
