For instance Series[Exp[x],…] gives you expansion of Exp[x]. But how would I obtain Exp[x] if I give a summation function?Read more
I am working on a real-time analytical system that uses a database schema which was designed without giving much thought to the performance. The current design is more like a flat table approach where we have the measurable fields and non-measurable fields all combined together in a single table. There is no intermediate layer betweenRead more
I have currently looked at imputeTS and zoo packages but it does not see to work Current data is.. group/timeseries(character) 1 2017-05-17 04:00:00 1 2017-05-17 04:01:00 1 NA 1 NA 1 2017-05-17 05:00:00 1 2017-05-17 06:00:00 2 NA 2 2017-05-17 04:31:00 2 NA 2 NA 2 NA 2 2017-05-17 05:31:00 I would like to fillRead more
In [1], Lin Weng shows that the Riemann hypothesis (RH) holds for certain linear combinations of shifted Riemann zetas. I would like to know whether these are all examples for which the RH is known. To be precise, we say that a Dirichlet series $ $ D(s)=\sum_{n=1}^\infty \frac{a_n}{n^s} $ $ satisfies the generalized Riemann hyporthesisRead more
how I can express correctely in one serie the following expresion $ $ \sum _{(k=-20) (k\neq 0)}^{20} -\frac{2 \left(\frac{3}{2} \pi \csc \left(\frac{1}{2} (2 \pi k+\pi )\right) \text{sech}\left(\frac{1}{3} \pi (2 k+1)\right)-\frac{2}{3} \pi \sec (\pi k) \text{sech}\left(\frac{3}{4} \pi (2 k+1)\right)\right)}{\pi ^2 k (2 k+1)^3}$ $ normaly I must to divide the expresion in two series from k=-infiniteRead more
I would like to plot the Taylor polynomials for several functions. Specifically: Exp[Sin[x]] ( x^2 + Exp[ x ] )^( -1 ) and Exp[ -4 x^2 + 5 x] I have their Taylor series as: taylorFunction1[x_, n_] := Normal[Series[f1[x], { x, 0, n} ] ] taylorFunction2[x_, n_] := Normal[Series[f2[x], {x, 0, n} ] ] taylorFunction3[x_,Read more
I really want both but I can only get one. I’m scared that I wont use them as often and that I’ll regret getting one rather than the other. I really like photography and I never used a proper camera before so I don’t know anything about cameras and how to properly use it. AndRead more
I have a large set of data recorded by a logging system which rotates at a fixed but unknown speed around an unknown location. The sensor has a very narrow field of view and each time the sensor “sees” an object the object records it’s location in two dimensions. The data set therefore consists ofRead more
Note: I am using 2*x+cos(x) as an example below. I’m asking this question for any function where Solve[] doesn’t yield a closed form result. My specific interest at the moment is getting Mathematica to spit out the (well known) power series expansion solution of Kepler’s Equation of the Center, just as a test. The functionRead more
