## Self-learning Trig? calculus?

Hi,
I'm a sophmore in high school, right now im in honors chemistry and algebra 2, (if you are familiar with science bowl, my school, mira loma, won last year)

I want to learn trig and eventually calculus on my own, with the hopes of understanding highschool and college level physics. I have an old textbook from my dad's study, its by Mcgraw hill and it says "Plane Trigonometry with Tables"(1974) is this a good textbook to learn from? If not what is a better method and what would be better for learning calculus and physics on my own?

Also, what are the REAL pre-req.s to learn calculus and trig because theres a lot of stuff I hear like Pre Calculus is not really related or used in Calculus, so what do I need to learn then?

 You can learn pre-calculus math(algebra, trigonometry, etc.) from online sources. Try this site out: http://www.themathpage.com/aPreCalc/precalculus.htm , continue through the topics until you understand everything there. I would say you need a good knowledge of the following: Trigonometry(sin, cos, tan, identities, etc.), exponents and exponential functions, logarithms and logarithmic functions, functions(of course), conic sections(ellipse, hyperbola, and parabola), sequences and infinite series, and so on. http://en.wikipedia.org/wiki/List_of...tric_functions You should memorize everything between tan = sin/cos up till related identities. Remember logbx = n and bn = x. To get the value of n you do: logx/logb(or logexponent/logbase) I'm sure you already memorized (-b +/- sqrt(b2 -4ac) /2a, sohcahtoa and etc. Like I said, check out http://www.themathpage.com/aPreCalc/precalculus.htm or http://www.youtube.com/khanacademy

 Quote by Char. Limit Especially check out khan academy. My advice is use Khan Academy to learn the material, then find somewhere to do practice problems.
You mean visit:

And then find somewhere else to do more practice problems

Everything in the review of this page is needed to learn calculus: http://tutorial.math.lamar.edu/Classes/CalcI/CalcI.aspx

Don't read the notes, they are short and brief, and are meant to be read after a book or supplement formal teaching. Mostly in calculus you should be good with manipulating equations and knowing the unit circle. You can probably even understand limits and derivatives now. Don't be afraid to jump into something.

Some people were saying to not worry about learning all this now. It is better to approach physics from a calculus perspective and will make you better with physics. The other way can be done too, just not as effective.
