    Approaching physics mathematically-help

    I am somewhat opposite to you, I find it easy to incorporate the math. Only difference is, my teacher says i should forget about the math and think more intuitively. I think this is a bad idea though so I will only take it for what its worth.

    Earth's gravitational field strength

    you do not need to know the mass of the second object. F=ma and the masses of the second object cancel out. a=9.8m/s^2 on Earth and at the point above the Earth a=9.8/3 let r=radius of Earth + altitude. then plug in and solve for a.

    Self-Taught Physics for High School Sophomore

    I am in high school also. I don't know anything about physics, But I don't see how you can study QM or much physics at all without any calculus. I suggest you study calculus and work hard on the maths. I like to see people like you with this type of enthusiasm, so get to work.

    Programs Just in pre-calc but want to major in EE. Advise?

    Don't worry about not having ap calc. in most cases, its much better that you wait for college and do the calculus right. you have to remember that ap calculus at a high school will most probably be different than calculus taught by a college professor.

    Linearization of an equation around fixed points

    example find the linearization of f(x)=x^2 about x=3 L(x)=f(3)+f'(3)(x-3) L(x)=9+6(x-3)=6x-9

    Linearization of an equation around fixed points

    linearization the linearization of a function f about a, (linearization at x=a) is L(x)= f(a)+f'(a)(x-a) Its pretty much like a taylor series approximation.

    How was the chain rule used to find the derivative of a trigonometric function?

    if i understand what you mean, they just used the chain rule for derivatives.

    Really basic stuff that I am confused on.

    1=1^(4/4)=(+-1^(2))^(2/4)=(+-1^(2))^(1/2)=+-1^(2/2)=+-1 Why exactly doesn't this work,other then you get -1=1, but other then that in the process. i don't exactly get what all this means or what you intend to do with it but i do know 1 is not equal to negative one. don't forget when you take...
