Different views of love. focusing on the tone of the poetry , comment on the interpretation of love in shakespeare's sonnets, donne's " a valediction forbiding mourning

In " A valediction forbiding mourning" Donne is speaking to his beloved showing love is not changed by distance.Though they have to separate he wants his beloved to believe that it does not mean they will not be together.For him love is not just physical proximity, it goes beyond that.For him love is like a convocation;sacred in some way so it will not alter.Crying should not be part of love when one of them has to leave, because love that is real can deal with separation.Love means that two sowls become one , even when kisses and tender caresses are not possible.He gives the idea that their love is like the feet of a compass, were one foot remains in the center and the other moves around it. In Shakespeare´s sonnets the views of love are different.He describes the love of frieds, true friends and also the love for women so different from the typical blond and blue eyed lady.He speaks in some other sonnet about  love that never "...Alters or bends with the remover to remove.."In his vision , true love never changes ,no matter what happens and, in this sense ,he has the same opinion about love as Donne.

. a function is a relation in which each input has only one output. in the relation , y is a function of x, because for each input x (1, 2, 3, or 0), there is only one output y. x is not a function of y, because the input y = 3 has multiple outputs: x = 1 and x = 2.
