 Oct12 comment Analytic region of $f(z)^{1/n}$ @mark Ah, you are right, f(z) is analytic Oct12 comment Analytic region of $f(z)^{1/n}$ I edited my post Oct12 comment Analytic region of $f(z)^{1/n}$ I'm looking for conditions on Real and Imaginary parts of f(z) so the non-analytic region could be derived Oct4 comment Find the range of values $k$ can take given that, for real $x$, $f(x) = \frac{x^2+3k}{x+k}$ Can you elaborate? Why taking the discriminant in the first place? Aug2 comment Whats wrong with this proof? What's wrong with $(-1)^2$ Aug2 comment Trigonometric function, with calculus integration. @DonAntonio I Reedited to sec^3 Aug2 comment Trigonometric function, with calculus integration. did you mean sec^3 or sec(x^3)? Aug1 comment Find the equation of a line @User58220 Sure,you are right.OP also said there are 4 cases.I'll update my post.Thanks:) Jul23 comment Positive integer multiples of an irrational mod 1 are dense Please clarify your title Jul12 comment Why isn't the factorial function defined for non-integers, but the gamma function is? (+1)Good question.I think it is just a game of definitions.Say, what is so important about multiplying numbers from 1 to n? Jun16 comment Need to find function by the data @user35443 Try "double(x)" : returns the double-precision value for X. If X is already a double-precision array, double has no effect. Jun16 comment Need to find function by the data @user35443 Hmm...Doesn't it mention type of variable with "whos" ? In Matlab 2012 there are double... Jun16 comment Need to find function by the data Yes. For example in "Exponential with 2 terms" substitute a for 28.49. And accept the answer if it is helpful Jun16 comment Laplace transform of $f(t)=10te ^{-5t}$ Well, Are you sure you want the "inverse" Laplace transform of "f(t)" Jun16 comment Laplace transform of $f(t)=10te ^{-5t}$ Is this your homework?math.stackexchange.com/questions/421778/… Jun16 comment What's the best way to calculate all of the points for a curve given only a few points? Have you seen these pages? en.wikipedia.org/wiki/Interpolation and en.wikipedia.org/wiki/Extrapolation Jun16 comment What's the best way to calculate all of the points for a curve given only a few points? What do you mean about "Backwards" and "the end points don't have any points on the outside? Jun15 comment How many possible iPhone passwords? @rbm Thanks for mentioning that Jun6 comment What is the difference between Beal's Conjecture and Fermat's Last Theorem? Slashdot and Texas Banker, huh? May26 comment What is the mathematical foundation of Control Theory? Thank you for the link
