Mathematics

Let

R = \{(P,Q) \mid P

and

Q

are at the same distance from the origin

\}

be a relation, then the equivalence class of

(1, - 1)

is the set

S = \left\{ (x,y) \mid x^{2} + y^{2} = 1 \right\}

S = \left\{ (x,y) \mid x^{2} + y^{2} = 2 \right\}

S = \left\{ (x,y) \mid x^{2} + y^{2} = 4 \right\}

S = \left\{ (x,y) \mid x^{2} + y^{2} = \right\}
