I want to note here, in special (or, general) relativity, our universe and the spacetime are interchangeable terms (For why, see this).  But, in reality,...

All nearest smaller values In a list of numbers $A$, the nearest smaller value (NSV) to an entry $A_i$ is the last entry preceding it with a smaller value, if any; that is, the entry $A_j$ with greatest $j < i$ such that $A_j < A_i$. The all nearest smaller values (ANSV) problem is that of computing the NSV for each n...

# How do you use the factor theorem to determine whether x+1 is a factor of x^3 + x^2 + x + 1? ##### 1 Answer Jan 3, 2016 The factor theorem states that a polynomial $f \left(x\right)$ has a factor $\left(x + k\right)$ if and only if $f \left(- k\right) = 0$. Here ${x}^{3} + {x}^{2} + x + 1$ is a polynomial. Let $f ...
