## Weekly outline

• ### General

Now that we all have our devices, all the knowledge you could ever want is right at your finger tips.  TRIG ISN'T EASY, it will take effort to learn!

If you are struggling with a problem shoot me an email and I will try and work it out on my IPad and post it for you that evening!
