Any advice or tips for going about it.

Read books on trigonometry.
Go through math websites that you feel can really help you in the topic.
Be dedicated to the subject. Don't pause midway if you find you don't like the subject. Decide if you really want to go ahead with trigonometry. It looks easy at first glance but there are some intricacies involved that have made many give up after some time as they found it too tough.
If you find a problem hard to do or there is a solution you can't understand, please ask someone. Self-learning does not mean you must do everything yourself and not take the help of others. The Answers Mathematicians are always there for you.

If you are reasonably bright, or mechanically inclined, trig is cake. Here's the whole of trigonometry: Take a piece of paper. Put an x and y axis on it. Go to the point x=1 and then draw a circle around the origin (0,0). If you plotted the value for x as a function of the angle, eg x=1 at angle=0, and x=0 at angle=90deg. This function is called cosine, it makes like a wave. If you plot y in the same way it's called sine. It's also a wave, just shifted 90degrees. The point is that with these silly curves and the use of similar triangles, we can find ALL the dimensions of ANY right triangle given only ONE side and the ANGLE. That's it really. There are some strange identities and the tangent function, but I'll let you look forward to that.

Think as a game,
write down all the formulations on a sheet and make some exercises by looking at that sheet, after a while you'll see that you already memorize them all.
And also to know the common values (sin 90, cos 180 etc) you should take a look at the unit circle, it helps a lot.

Here is a formulation guide:

I did it, but I really don't recommend it. While looking back I can say the concept is simple, it was definitely challenging to do. I wanted to get ahead in math so I skipped Geometry, and included in geometry is trig, so it worked out that way. I would recommend you talk to someone that knows a lot about trig before committing to anything. I had my dad, who helped a lot. I know people that have taken 4 years of math and still don't understand trig, so just be careful. I really really like trig, but a lot of people just don't get it. If you're not good with abstract concepts, stay away from teaching yourself trig or anything more advanced down the line (that goes for online math classes too--NEVER take one, regardless of your skill level!). The underlying problem with most people who are trying to teach themselves trig is that they're not dedicated enough. If you don't HAVE to do it, people generally don't.

Its just forming a right triangle with the given data and the ratios like sin,cos and tan...
sin : Old Hardy (Opp side/Hyp)
cos : And His (Adj side/Hyp)
tan : Old Aunt (Opp side/Adj side)
(remember tan=sin/cos)
Now find the reciprocals for the above
1/sin = cosec
1/cos = sec
1/tan = cot
And for the quadrants remember ASTC( All silver Tea Cups) when you represent an value in a 2D graph

read trigonometry books, web pages.
search google and its trig. books.
Ask me the difficult questions immediately.
