    en.wikipedia.org/wiki/Microsoft_Math_Solver

    Microsoft Math contains features that are designed to assist in solving mathematics, science, and tech-related problems, as well as to educate the user. The application features such tools as a graphing calculator and a unit converter. It also includes a triangle solver and an equation solver that provides step-by-step solutions to each problem.

  3. Equation solving - Wikipedia

    en.wikipedia.org/wiki/Equation_solving

    Depending on the context, solving an equation may consist to find either any solution (finding a single solution is enough), all solutions, or a solution that satisfies further properties, such as belonging to a given interval. When the task is to find the solution that is the best under some criterion, this is an optimization problem. Solving ...

  4. How to Solve It - Wikipedia

    en.wikipedia.org/wiki/How_to_Solve_It

    Pólya mentions that there are many reasonable ways to solve problems. [3] The skill at choosing an appropriate strategy is best learned by solving many problems. You will find choosing a strategy increasingly easy. A partial list of strategies is included: Guess and check [9] Make an orderly list [10] Eliminate possibilities [11] Use symmetry [12]

  5. Quadratic formula - Wikipedia

    en.wikipedia.org/wiki/Quadratic_formula

    Using this approach, solving a polynomial of degree ⁠ ⁠ is related to the ways of rearranging ("permuting") ⁠ ⁠ terms, called the symmetric group on ⁠ ⁠ letters and denoted ⁠ ⁠. For the quadratic polynomial, the only ways to rearrange two roots are to either leave them be or to transpose them, so solving a quadratic polynomial ...

    For the expansion, if the reflection point is the new minimum along the vertices, we can expect to find interesting values along the direction from to . Concerning the contraction , if f ( x r ) > f ( x n ) {\displaystyle f(\mathbf {x} _{r})>f(\mathbf {x} _{n})} , we can expect that a better value will be inside the simplex formed by all the ...

  9. Quartic reciprocity - Wikipedia

    en.wikipedia.org/wiki/Quartic_reciprocity

    Quartic or biquadratic reciprocity is a collection of theorems in elementary and algebraic number theory that state conditions under which the congruence x 4 ≡ p (mod q) is solvable; the word "reciprocity" comes from the form of some of these theorems, in that they relate the solvability of the congruence x 4 ≡ p (mod q) to that of x 4 ≡ q (mod p).
