I would like to know how can I derive the double, half, product to sum, and sum to product identities of trigonometry using simple algebraic means.
And which books (which I prefer) should I pickup at the library on this subject to actually learn these derivations? Or at the very least some videos?
I don't like reading text online, I find it hard to follow and very passive and unengaging in my opinion.
Thanks in advance.
