The National 5 Maths exam, sat on 12 May 2016, in particular Paper 1 (non-calculator), was also criticised by students after being considered much more difficult than previous years. A petition was created by students which was to be sent to the SQA demanding to know why the exam was exceedingly difficult, and it gained over 25,000 signatures. [19]
The content ranges from extremely difficult algebra and pre-calculus problems to problems in branches of mathematics not conventionally covered in secondary or high school and often not at university level either, such as projective and complex geometry, functional equations, combinatorics, and well-grounded number theory, of which extensive knowledge of theorems is required.
(July 2023) (Learn how and when to remove this message) The circular restricted three-body problem [ clarification needed ] is a valid approximation of elliptical orbits found in the Solar System , [ citation needed ] and this can be visualized as a combination of the potentials due to the gravity of the two primary bodies along with the ...
The Mahalanobis distance is a measure of the distance between a point and a distribution, introduced by P. C. Mahalanobis in 1936. [1] The mathematical details of Mahalanobis distance first appeared in the Journal of The Asiatic Society of Bengal in 1936. [2]
World Maths Day (World Math Day in American English) is an online international mathematics competition, powered by Mathletics (a learning platform from 3P Learning, the same organisation behind Reading Eggs and Mathseeds). [1]
The 2023 Nigerian currency crisis was precipitated in January 2023 by a shortage of naira cash amid an attempt by the Nigerian government to force citizens to use newly-designed notes, which the government said would help stem the tide of vote-buying in the lead-up to the 2023 general elections. This led to extensive street protests throughout ...
In mathematics, he is known for his work in number theory, including the calculation of π and Størmer's theorem on consecutive smooth numbers. In physics, he is known for studying the movement of charged particles in the magnetosphere and the formation of aurorae , and for his book on these subjects, From the Depths of Space to the Heart of ...
If an airplane's altitude at time t is a(t), and the air pressure at altitude x is p(x), then (p ∘ a)(t) is the pressure around the plane at time t. Function defined on finite sets which change the order of their elements such as permutations can be composed on the same set, this being composition of permutations.
