    The United States National Chemistry Olympiad (or USNCO) is a contest held by the American Chemical Society (ACS) used to select the four-student team that represents the United States at the International Chemistry Olympiad (IChO). Each local ACS section selects 10 students (or more for larger ACS sections) to take the USNCO National Exam.

  3. Differential calculus - Wikipedia

    en.wikipedia.org/wiki/Differential_calculus

    In mathematics, differential calculus is a subfield of calculus that studies the rates at which quantities change. [1] It is one of the two traditional divisions of calculus, the other being integral calculus—the study of the area beneath a curve.

    Thanaweya Amma (Arabic: ثانوية عامة ) is a series of standardized tests in Egypt that lead to the General Secondary Education Certificate for public secondary schools and serves as the entrance examination for Egyptian public universities.

  5. Homework - Wikipedia

    en.wikipedia.org/wiki/Homework

    The intention of homework is to further test students' knowledge at home. However, there is a line between productive work and busy work. Busy work has no inherent value; it just occupies time. Karin Chenoweth provides an example of a student taking chemistry who must color a mole for homework. [13]

    In 2014, the Board of Regents created the 4+1 option, where students must pass at least 4 regents exams—one per subject—and pass one additional approved pathway option. Students must score 65 or higher in English Language Arts, one mathematics exam, one science exam, one social studies exam, and one more exam of their choice.

  8. Cubic equation - Wikipedia

    en.wikipedia.org/wiki/Cubic_equation

    The rational root test allows finding q and p by examining a finite number of cases (because q must be a divisor of a, and p must be a divisor of d). Thus, one root is x 1 = p q , {\displaystyle \textstyle x_{1}={\frac {p}{q}},} and the other roots are the roots of the other factor, which can be found by polynomial long division .

  9. Mathematical formulation of quantum mechanics - Wikipedia

    The result is a causal chain, the primary cause in the past on the utmost r.h.s., and finally the present effect on the utmost l.h.s. .) The Heisenberg picture of quantum mechanics focuses on observables and instead of considering states as varying in time, it regards the states as fixed and the observables as changing.
