    You're right, I did mistakenly mix a few concepts together. The series representation for the function is infinite, like you say. What I was misapplying was the idea that a converg…

    My memory is fuzzy on the details, but there's a way to show that if you have a series representation of a function that equals that converges to a=that function (i.e., an infinite…

    Matrix functions (at least ones I learned about way back when) are Taylor series representations of a function with the matrix plugged in. For example: exp(A) = I + A + A^2/2 + ...…

    I think it's a typo. \int_a^x f'(t)dt should be f(x) - f(a), and that would be the fundamental theorem of calculus (or some corollary of it). It looks like either f(a+x) should be …
