Parametrize y = sin(x) with i^ j^ components

    I am having a hard time understanding how to parametrize the function y = sin(x) into component form (i,j).

    Hey kgal and welcome to the forums.

    Hint: let x = t.

    Thanks,

    is it r(t) = ti^ +sin(t)j^ ?

    As long as y is a function of t, y= f(t), there is the "trivial" parameterization, x= t, y= f(t) or, in vector terms [itex]t\vec{i}+ f(t)\vec{j}[/itex].
