1. ## I need help!

I've got my key stage 3's next week and I've just found out today that I'm being put in for the hardest maths paper. I also found out that I need to have an advanced understanding of trigonometry, but I haven't the faintest what trigonometry is. I know Pythagoras theorm and stuff like that, it's just things like sine, etc. that I don't know. If someone could post some help, or even post a link to where I could get help, I'd really appreciate it.

2. you dont know sine, cosne, and tangent!?!?

Well, i will teach you :)

Here is a saying:
Oh Heck Another Hour Of Algeba

Oh Heck=(x is the angle) X sin=opposite side/hypotnuse

the -1 buttons work when you only have the sides and your trying to find the angle

Im not sure this will help, or if this is what you even what (maybe i have just made a fool of myself?) but yea, thats what i use

EDIT- heres a nice pic

3. Thanks for the quick response. It's late now, so I'm gonna print it off and read it tomorrow.

4. I think I've got it now. I asked my maths teacher and she gave me some sheets, and the way she told me to remember it was just with SOH CAH TOA for Sin = opp/hyp, cos = adj/hyp and tan = opp/adj. Then I put Tan^-1 1 (for example) into my calculator and I get an angle of 45 degrees. Thanks for the help anyway. If this were Gamerenders I'd +rep you and donate some points.
