Post Analytic geometry?
Hi. I need some help. I'm trying to learn how to make polynomials simpler by changing axes by translating and rotating them, as in eliminating the xy terms in a conic and then finding out how far the rotated conic is translated from the origin. I must have missed the simpler stuff even in high school. For instance I've seen the formula for simplifying a conic as cot(2 theta) = (a-c)/b for the polynomial ax^2 + bxy + cy^2 + dx + ey + f = 0 but I have no idea how this formula was inspired or derived. I'm looking for the best book that money can buy to teach me how to simplify polynomials using these techniques. So my question is what books do you recommend for learning this for the first time. Note that I've essentially missed a formal public school education in trigonometry, geometry, analytic geometry, precal and conic sections so a book that included those basics would be okay as well if it also has what I want about simplifying polynomials. I'm not necessarily looking for a less advanced book but I do want a book that doesn't assume that I know all the basics already, and I love graphics. I would consider buying both a beginning and really advanced book too. Recommended books?
