Aug 27, 2014 · I am trying to understand why $\\sqrt[3]{x}$ is an odd function; can anyone explain how I could come to this conclusion?

This MATLAB function returns the real nth root of X.

Aug 15, 2016 · Yes, yes, but some people are pedants, and impose on the real cube root the same domain restriction as the real square root, even though the former is bijective across the …

Matrix Cube Root Find matrix B, such that B3 = A, where A is a 3-by-3 identity matrix. To solve B3 = A, compute the cube root of the matrix A using the funm function. Create the symbolic …

Mar 26, 2013 · At some point of my calculations some cube roots are introduced and unfortunately Matlab seems to automatically simplify terms like (-1)^ (1/3) to yield 0.5000 + …

Nov 24, 2021 · Be very careful though. If x is negative, it will return a complex number, because there are indeed THREE cube roots of a negative number. Two of them are complex. nthroot …

Jan 22, 2020 · since it can also be written as x^(1/3) and therefore 1/(x^3) and this would not make sense for x=0 because of the division with 0. So why is 0 in the domain?

Apr 7, 2022 · I've got this cubic function that I can't figure out how to calculate its inverse. $$f (x)=x^3+3x^2+3x, x\in \mathbb {R}$$ I've tried using online calculator to see if that would help, …

Nov 14, 2018 · I need to solve Z^3 = -8-3i, and obtain all cube roots of -8-3i showing that the sum of the cube roots is zero using matlab.

Oct 9, 2021 · For cubics, they can have one stationary point at x = h x = h. But I also know that a cube root function is the inverse of a cubic function, hence it can also have 0 0 or 2 2 …
