How many of you grade schoolers have said to yourself: "Man, algebra is SO hard". This is first year calculus kids. Algebra is easy. ------------------------------------------------------------------------- A painting in an art gallery has height h and is hung so its lower edge is a distance d above the eye of an observer (as in the figure). How far from the wall should the observer stand to get the best view? (In other words, where should the observer stand so as to maximize the angle subtended at his eye by the painting?) Your answer may depend on h and d. ------------------------------------------------------------------------- Yes I'm fine. - @gamesquad186 Comment your answer below. :P
