Thread: Trigonometry

Hi, I would like to learn trigonometry in advance, for personal interest and fun.


I would like if someone could point me out some trigonometry problems and explain me it's principals and how to solve them, if it's not too much to ask.

Even a link would be fine.

Thank you,
L.E.A.P

Just go to the library and pick up a text book (public libraries will probably suffice)? You're still in high school, if they have spare coursebooks, your math teachers probably wouldn't mind you getting a head start.

Though I'd have to ask why bother? You will be taking trig eventually no? Unless you plan to have excessive difficulties or really have a need to know it before hand, why not use your spare time now for something more fun, like number theory?

Also the resources you can get to on the web with just a google are really good on the topics of math and science. So google trigonometry and be amazed.

I would take shmoe's advice to just learn something else. If not, you'll be very bored in class if you already know the material and do not feel all that motivated to do anything else during that time.

If you really want something to do, try doing what I did in high school: take two math classes at a time. I was probably the only student ever at that school that took geometry and alegbra at the same time for fun. Everyone else that had to do it required that for graduation. At the end of the year, I had 5 math credits instead of 4.

Though take a look at number theory. All you really need to know (very basically, anyway) is algebra. It would help to know how to prove conjectures, but you could always learn this on the way or ask some of your teachers.

This semester I am taking number theory. It's not all that hard, but very interesting. Just for fun, by definition of divisibility, zero divides zero. Also you could learn how to disprove things like "the triple prime conjecture." From the outside, these things seem wild and hard. But when you get a little bit into it, it's easy and fun. 8)

Good luck. Let us know what you want to do.

dont listen to them. go ahead with trigometry, and when you work with that in school work with other kind of math. allways be ahead of the class

thats how i have done my entire life. of course now i am beyond any math i´ll learn in the school im currently in but hey its fun

If you learn it now, then later it will be one less subject to revise when the crunch comes. You will always find in class there is some small point you missed - going through it twice is no bad thing.

I'd start with Wikipedia and Mathworld. If you know enough algebra to read what's in those articles, there's a lot of good information there.

Specifically, look at the entries for Sine, Trigonometry and Trigonometric identities. A lot of trigonometry is recognizing and applying such identities.

Not sure if they still use it but SohCahToa is the word to remember. :wink:

billco they still use it, thats how I've learnt triginometry, except I'm in extention maths so some people in my grade have only learnt Tan, were the extention classes have also done Sin and Cos. Remember H for hypotenuse ^.^

Ahh, good old reliable old Pythagorus!

Nice to see quantum physics has not overturned him yet! :wink:

yup...^.^ pythagoras is your freind once you get the hand of the whole triangles into sqaures idea.
