The derivative function (blue) crosses the x-axis where the original function (green) has a relative minimum. The above image demonstrates an important result of the fundamental theorem of algebra: a polynomial of degreenhas at mostnroots.Roots (or zeros of a function)are where the function c...

a.a mathematical expression consisting of a sum of terms each of which is the product of a constant and one or more variables raised to a positive or zero integral power. For one variable,x, the general form is given by:a0xn+a1xn–1+ … +an–1x+an, wherea0,a1, etc, are real ...
This is essentially a simplified version of a cylindrical algebraic decomposition but with one major restriction which is that it is only for strict inequalities and not equations or non-strict inequalities. Note that even if sympy had CAD it would be useful to have a function like this because...
The function f(x) may assume a variety of nonlinear functionalities ranging from that of a polynomial equation whose canonical form is: (1.11)f(x)=anxn+an−1xn−1+…+a1x+a0=0 to transcendental equations, which involve trigonometric, exponential, or logarithmic terms. The roots of these...
eval("-2x^3+10x-4x^2","3")=-60eval("x^3+x^2+x","6")=258 Description of issue: In this code I break the string into a substring whenever a +/- is encountered and pass the substring to a function which evaluates single term like "-2x^3". So my code for input = "-2x^...
From the perspective of the function space, the pdf can be regarded as a vector in the second-order probability space (Ω,F,P), so the form of coordinates and basis functions can yield: (4)f(ξ)≈∑α∈Ifˆαϕα(ξ) If this expansion can achieve spectral accuracy, it can also...
Definitions: The Vocabulary of Polynomials Cubic Functions – polynomials of degree 3 Quartic Functions – polynomials of degree 4 Recall that a polynomial function of degree n can be written in the form: Definitions: The Vocabulary of Polynomials Each monomial is this sum is a term of the polyn...
Although the order of the terms in the polynomial function is not important for performing operations, we typically arrange the terms in descending order of power, or in general form. The degree of the polynomial is the highest power of the variable that...
Every vectorial Boolean function F in n variables that is a function from F2n to F2n can be uniquely represented in the univariate polynomial form (or polynomial representation) over F2n of degree not more than 2n − 1: F(c)=∑j=02n−1ajcj,whereaj∈F2n. Indeed, the number of ...
