before that, i need someone to explain how newton's third law can be applied to lift, since Bernoulli effect has a smaller influence. Since the aerofoil pushes against the air, so what? Wouldnt there simply be a drag force? Where does the lift come from?

Ok, here's the question i need help with.
1. Why Frisbees fly (i guess i can do it nicely in terms of Bernoulli principle, but i want to know the Newton's way.)
2. Why do Frisbees fly in a more controlled manner when they are spinning.
*
Here's a guess for 2. I read beforehand that if u hold the centre of a wheel of a bike and asked someone else to spin it, u will feel a mysterious force if u try to tilt it to anyway. I cant visualize it, but i can understand what they mean by tilting it is changing its direction and so the angular velocity changes, which constitutes a force. Hope there is some way u can help me in my understanding..=)

(i know its a lot to deal with here, sorry...a good answer gets my ten points)

I see a lot of trig questions on here. Mostly, they have sine, cosine, and tangent. What are they?

And what do people mean by sin 33.3 or something like that?

P.S. I'm a seventh grade geometry freak.
