How to prove trigonometric identities step by step?

To prove a trigonometric identity, we always start from either the left hand side (LHS) or the right hand side (RHS) and apply the identities step by step until we reach the other side. However, smart students always start from the more complex side.

Does the trigonometry proving miracle really happen?

More often than not, the miracle does not happen. This is because most proving questions revolve majorly around good old expansion, factorization, simplification and cancelling of like terms. In fact, some proving questions do not even require student to use any trigonometry rules at all.
