Question

Find the distance of a point p with coordinates x, y from its origin

Answer 1

Let o be the origin with(0,0)coordinates. And P (x, y)
There fore,by distance formula
OP={(x-0)+(y-0)}^1/2
={x+y} ^1/2



Note:^1/2=under root

Answer 2

The origin (0 ,0) .
given points of point p=(x y)
so distance between two points (a b) and (p q) is given by root of (a^2-p^2)+(b^2-q^2).
so distance between origin and point p
=square root of x^2+y^2
