  2. Learning Tools Interoperability - Wikipedia

    en.wikipedia.org/wiki/Learning_Tools...

    Learning Tools Interoperability (LTI) is a standard developed by 1EdTech formerly known as IMS Global Learning Consortium at the time of creation. It enables seamless integration between learning systems and external systems. [1] In its current version, v1.3, this is done using OAuth2, OpenID Connect, and JSON Web Tokens.

    This screenshot shows the formula E = mc 2 being edited using VisualEditor.The window is opened by typing "<math>" in VisualEditor. The visual editor shows a button that allows to choose one of three offered modes to display a formula.

  4. Calculus - Wikipedia

    en.wikipedia.org/wiki/Calculus

    In mathematics education, calculus is an abbreviation of both infinitesimal calculus and integral calculus, which denotes courses of elementary mathematical analysis.. In Latin, the word calculus means “small pebble”, (the diminutive of calx, meaning "stone"), a meaning which still persists in medicine.

  5. Geometric series - Wikipedia

    en.wikipedia.org/wiki/Geometric_series

    Each side of the green triangle is exactly ⁠ 1 / 3 ⁠ the size of a side of the large blue triangle and therefore has exactly ⁠ 1 / 9 ⁠ the area. Similarly, each yellow triangle has ⁠ 1 / 9 ⁠ the area of a green triangle, and so forth. All of these triangles can be represented in terms of geometric series: the blue triangle's area is ...

    Early rounds of his deposition show him offering obfuscatory answers and saying "I don't recall" so many times that even the presiding judge had to chuckle. Worse, many of the technology chief's denials and pleas of ignorance were directly refuted by prosecutors with snippets of e-mail that Gates both sent and received.

  7. Complex number - Wikipedia

    en.wikipedia.org/wiki/Complex_number

    A complex number can be visually represented as a pair of numbers (a, b) forming a vector on a diagram called an Argand diagram, representing the complex plane. Re is the real axis, Im is the imaginary axis, and i is the "imaginary unit", that satisfies i 2 = −1.

  8. Fermat's Last Theorem - Wikipedia

    en.wikipedia.org/wiki/Fermat's_Last_Theorem

    The Fermat–Catalan conjecture generalizes Fermat's last theorem with the ideas of the Catalan conjecture. [ 167 ] [ 168 ] The conjecture states that the generalized Fermat equation has only finitely many solutions ( a , b , c , m , n , k ) with distinct triplets of values ( a m , b n , c k ), where a , b , c are positive coprime integers and ...

  9. Pi - Wikipedia

    en.wikipedia.org/wiki/Pi

    The number π (/ p aɪ / ⓘ; spelled out as "pi") is a mathematical constant, approximately equal to 3.14159, that is the ratio of a circle's circumference to its diameter.It appears in many formulae across mathematics and physics, and some of these formulae are commonly used for defining π, to avoid relying on the definition of the length of a curve.
