MHB Most Important Precalculus Topics

AI Thread Summary
Key precalculus topics essential for success in Calculus 1 include a strong understanding of trigonometry, basic geometric facts, and analytic geometry. Mastery of algebra is crucial, particularly in solving linear and quadratic equations and finding polynomial roots. Familiarity with the relationship between function equations and their graphs is also important. Resources like Stewart's Calculus textbook can provide diagnostic exams to assess readiness. A solid foundation in these areas will significantly enhance a student's ability to tackle calculus concepts effectively.

In your opinion, what are the most important topics in precalculus needed before entering calculus 1? What must a student know well after taking precalculus?

Definitely need to know your trig really well. See http://mathhelpboards.com/trigonometry-12/trigonometry-memorize-trigonometry-derive-35.html for some help on that. You need to know basic geometric facts like areas of squares, rectangles, triangles, and trapezoids. You need analytic geometry - so you're very familiar with going between the equation defining a function and its graph. You also need a significant mastery of basic algebra: finding roots of polynomials, solving equations including linear and quadratic. If you look at Stewart's Calculus book, he has a Diagnostic Exam in the beginning that should help you understand very well what the most important things to know are.

Thanks but I was looking for a list. I am now waiting for my James Stewart textbook to arrive in the mail. I think precalculus is super cool. It covers so many interesting topics that most students need to master.

By the way, the great calculus professor, James Stewart, passed away in December 2014.
 
Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...
Fermat's Last Theorem has long been one of the most famous mathematical problems, and is now one of the most famous theorems. It simply states that the equation $$ a^n+b^n=c^n $$ has no solutions with positive integers if ##n>2.## It was named after Pierre de Fermat (1607-1665). The problem itself stems from the book Arithmetica by Diophantus of Alexandria. It gained popularity because Fermat noted in his copy "Cubum autem in duos cubos, aut quadratoquadratum in duos quadratoquadratos, et...
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
