Determine if function is continuous
WebSorted by: 2. Continuity of a function is defined if it is continuous in the entire domain , such that for every a , f ( a) = lim x → a f ( x) should exist . Now for g ( x) you can verify that the function will be continuous at every point for a ≠ 0 ie you can verify that if a ≠ 0 then lim x → a s i n ( x) x = s i n ( a) a which is ... Web5. Yes, you can do this in a way via MuPAD 's discont function, which lists the discontinuities of a function. MuPAD functions can be called from within Matlab. For example: syms x; f = 1/ (x* (x-1)); feval (symengine,'discont',f,x) returns [ 1, 0], the two poles of f. If you want to bound your search domain, one way to do so is via assumptions.
