  2. Generating function - Wikipedia

    en.wikipedia.org/wiki/Generating_function

    The asymptotic growth of the coefficients of this generating function can then be sought via the finding of A, B, α, β, and r to describe the generating function, as above. Similar asymptotic analysis is possible for exponential generating functions; with an exponential generating function, it is ⁠ a n / n!

  3. Trigonometric functions - Wikipedia

    en.wikipedia.org/wiki/Trigonometric_functions

    Basis of trigonometry: if two right triangles have equal acute angles, they are similar, so their corresponding side lengths are proportional.. In mathematics, the trigonometric functions (also called circular functions, angle functions or goniometric functions) [1] are real functions which relate an angle of a right-angled triangle to ratios of two side lengths.

  4. Additional Mathematics - Wikipedia

    Section B contains 4 questions where students are given the choice to answer 3 out of 4 of them. Section C contains 4 questions where students are only required to answer 2 out of 4 of the given questions. All Section C questions are based on the same chapters every year and are thus predictable.

  5. Percentile - Wikipedia

    en.wikipedia.org/wiki/Percentile

    Physicians will often use infant and children's weight and height to assess their growth in comparison to national averages and percentiles which are found in growth charts. The 85th percentile speed of traffic on a road is often used as a guideline in setting speed limits and assessing whether such a limit is too high or low.

  6. 6 - Wikipedia

    On most phones, the 6 key is associated with the letters M, N, and O, but on the BlackBerry Pearl it is the key for J and K, and on the BlackBerry 8700 series and Curve 8900 with full keyboard, it is the key for F; The "6-meter band" in amateur radio includes the frequencies from 50 to 54 MHz

  7. Cosmic inflation - Wikipedia

    en.wikipedia.org/wiki/Cosmic_inflation

    Inflation answers this question by postulating that all the regions come from an earlier era with a big vacuum energy, or cosmological constant. A space with a cosmological constant is qualitatively different: instead of moving outward, the cosmological horizon stays put. For any one observer, the distance to the cosmological horizon is ...

  8. Taylor series - Wikipedia

    en.wikipedia.org/wiki/Taylor_series

    The Taylor series of any polynomial is the polynomial itself.. The Maclaurin series of ⁠ 1 / 1 − x ⁠ is the geometric series + + + +. So, by substituting x for 1 − x, the Taylor series of ⁠ 1 / x ⁠ at a = 1 is

  9. Coccolithophore - Wikipedia

    en.wikipedia.org/wiki/Coccolithophore

    [85] [86] Unraveling these fundamental constraints and the limits of adaptation should be a focus in future coccolithophore studies because knowing them is the key information required to understand to what extent the calcification response to carbonate chemistry perturbations can be compensated by evolution.
