I've recently gotten hold of this book, "The Art and Craft of Problem Solving", by Paul Zeitz. I have heard many recommondations for it, and think it is fantastic.
I want to read it the most effective way. Have any of you read it? How did you do it, or do you have any tips on how to read...
Just a question... to learn math/physics, is it better to do ~10 medium-challenging problems that invoke some thought, or doing 2-3 really hard problems that require deep thought and lots of time. Up to now I've been doing both, but it just isn't possible to keep up with UT's supplementary...

I'm a 4th year undergraduate physics major and I've realized too much of my college career have I just tried to get to the answer, copy example patterns, and look for a systematic way to solve problems. I realize this will get me nowhere; problem solving is where the physics fun is!

#1: The tangent at a point P on the curve y = x^3 intersects the curve again at a point Q. Show that the slope of the tangent at Q is four times the slope of the tangent at P.
So far, I found the derivative of y = x^3, which is y' = 3x^2. Now I set these two equal to each other:
X^3 = 3x^2...

Find numbers a, b, and c so that the graph of f(x) = ax^2 + bx + c has x-intercepts at (0,0) and (8,0) and a tangent with slope 16 where x = 2.
I have done this so far:
f(x) = ax^2 + bx + c
f '(x) = (2)(a)(x) + b
16 = (2)(a)(2) + b
16 = 4a + b
