I am trying to learn trigonometry(not in school)

and I can't find many sources on it... can somebody tell me where some maths referances are??

Thanks,
Dennis

You new signature is very interesting partly due to the fact that you misspelt signature.

Second time I've do this to you

And all because you're a little reluctant in bed...

I would have never guessed...... what a nice couple :D

Oh, V(ery) - someone asked about putting bitmaps in menus a few days ago - thought I'd point it out since it's your "speciality" :)

PS: John still remembers MLP :eek:

Trigonometry is using parts of the triangle to find out other parts using è as the angle A as Adjcent, O as oppersite and H as Hypotinous the

sin è = O/H

Cos è = O/H

Tan è = O/A

soh coh toa for short so if u have the lengths of any 2 sides or one side and the angle of a right handed triangle u can work it out using a scientific calculator

Um...Robbo?

Cos = Adjacent/Hypotenuse... ;)

Or, as one of our maths teachers put it:

Oranges and Apples are Tasty
Apples Have Cores
Oranges Have Skins

Which is a way to remember:

O/A = Tan x
A/H = Cos x
O/H = Sin x

Or as I put it - "Read the damn formula book"

We get one in the exam cos there's so much stuff to learn.

The best way to learn is with a teacher. Try taking a class at a local college or university.

listen 2 sam........

Learn the indentities. You don't need to know all of them.
In fact, once you get really comfortable with trig and other
forms of math, you only need to know a few identities with
which you can use to derive everything else.......

One place where students have problems in math is not
knowing the fundamentals. Trig identities greatly help a
Calculus student, Calculus greatly helps a student who
studies transform theory.

Like I said earlier, memorize some of the trig identities
which are the basis for extended identities. If you would like a list of the ones which mainly everything else can
be derived from, let me know.
