Why do some people bother to post broad meaningless statements as if they had a point to make when they don’t?
Because you are worth no more than a broad, true statement.
I don't try to teach trig to 3-year-olds either.
LOL. You clearly confused your lack of ability with a lack of willingness.
The reason you are unable to teach has nothing to do with my ability to learn.
It has everything to do with the fact that you cannot impart what you do not possess.
