### Graphing a function

A function is defined in a article equation 37, $$A(t)= 0.456+\frac{2.58}{(1+0.136 t)^{0.249}}$$ The simulation of the equation is: But I have tried like by this: ...

### Switching from Mathematica to MATLAB: As a text editor?

I have been using Mathematica for almost a year, and the most indispensable feature in Mathematica to me has been the ability to write really nice documents and print them into PDF or TEX files. In ...

### How to visualize a function to aid in optimization?

I am working on minimization of a function with more than two parameters. I want to see variations, local extremes, saddle points, etc. of this function to get some idea of how is this function in ...

### Plotting graphs using numerical/mathematica method

From the author's equation 13, 14 We can write by inserting V''(A)=0, Solving for R we get, $$R= \frac{6^{D/4} \sqrt{D}}{\sqrt{-2^{1+\frac{D}{2}} 3^{D/2}+3 2^{1+D} A-3^{1+\frac{D}{2}} A^2}}$$ Now ...

### WolframAlpha functionality: Computing nested integrals

Can wolframpalpha support the numerical calculation of the following type: $$\int_{x=0}^\infty f(x) e^{\int_{z=0}^\infty g(x,z)dz} dx$$ Note that the inside integral is in such form where ...

### What are the available libraries or programs for finding extremes of a function with no symbolic definition?

In my current mathematical inquiry, I would like to gain insight on behaviour of a $d$-dimensional continuous function by locating its maximum over the hyperplane $\sum_{i=1}^d x_i = 1$ for $x_i$ non-...
