Remember ALL the double angle formulas in secs! | (sin 2θ, cos 2θ, tan 2θ)

Hi, as a teacher I have often come across students finding it difficult to remember the double angle formulas for sin, cos and tan; in this video I have explained the easiest way to get all these formulas from just two formulas.
