3. A particle moves along a path such that its radius vector is given by f(t) = a sin(kt) ê, + b cos(kt) ê, where a, b, and k are constants. Show that the path is an ellipse of axes 2a and 2b. Show also, by expressing the acceleration in terms of the vector 7, that the acceleration is directed toward the origin at all times
