    The program was renamed to National Talent Search Scheme with the NTSE examination now being conducted for classes X, XI, and XII. Currently, the NTSE exam is conducted only for 10th class students in India in two phases with subjects relating to Mental Ability Test and Scholastic Aptitude Test (SAT) for 100 marks each. [6] [7]

    Because of this, often, the only simple effective way to deal with multiplication by expressions involving variables is to substitute each of the solutions obtained into the original equation and confirm that this yields a valid equation. After discarding solutions that yield an invalid equation, we will have the correct set of solutions.

    The report called on all parties within the industry to work together to find productive solutions, which included a movement toward open textbooks and other lower-cost digital solutions. Textbook prices are considerably higher in law school. Students ordinarily pay close to $200 for case books consisting of cases available free online.

  6. Singular solution - Wikipedia

    en.wikipedia.org/wiki/Singular_solution

    A singular solution in this stronger sense is often given as tangent to every solution from a family of solutions. By tangent we mean that there is a point x where y s (x) = y c (x) and y' s (x) = y' c (x) where y c is a solution in a family of solutions parameterized by c. This means that the singular solution is the envelope of the family of ...

    A unit distance graph with 16 vertices and 40 edges. In mathematics, particularly geometric graph theory, a unit distance graph is a graph formed from a collection of points in the Euclidean plane by connecting two points whenever the distance between them is exactly one.

    This will cover children of ages 3–7 years. The focus of studies will be in activity-based learning. Preparatory Stage: Classes 3 to 5, which will cover the ages of 8–10 years. It will gradually introduce subjects like speaking, reading, writing, physical education, languages, art, science and mathematics.

  9. Viscosity solution - Wikipedia

    en.wikipedia.org/wiki/Viscosity_solution

    The three basic properties of viscosity solutions are existence, uniqueness and stability. The uniqueness of solutions requires some extra structural assumptions on the equation. Yet it can be shown for a very large class of degenerate elliptic equations. [4] It is a direct consequence of the comparison principle. Some simple examples where ...
