Geo Analitica.



Galera, alguem poderia explicar pra mim como se faz esse problema (é bem simples, mas no livro a teoria esta um pouco jogada)

Given two points P and Q, a units apart, and the function
f(M)=(d_1)^2-(d_2)^2, where d_1=MP and d_2=MQ. FRind the expression
for this function when the point P is chosen as the origin, and the axis Ox is directed
along the segment PQ.

valeu

abraço
