You can look at this video to get an idea     

https://www.khanacademy.org/math/trigonometry/basic-trigonometry/basic_trig_ratios/v/basic-trigonometry

BUT

It is really important that you concentrate on the earlier work that I have given you.

Without a VERY solid grounding in the fundamentals you will NEVER really be a Maths God.
