There are many sorts of substances in skincare items which can be considered to be potentially bad for health and the skin generally speaking. For example, DEA (diethanolamine), MEA (monoethanolamine), and TEA (triethanolamine) are often used to balance the pH of several skin care products. Derma Hydrate Nevertheless, these are known to trigger allergic reactions, eye discomfort, and dryness of the hair. These components are also banned as a result of effects in Europe. Terrifying, huh?

How To Make Skin Look Young - I Have Simply Discovered The Key!
Skin care that is good is equally as critical as your overall body health. Unfortunately, many individuals are unsure of how to preserve their skin-healthy. Keep reading to discover the top skin care suggestions decorate and to protect your skin.

But, I obtained out my creditcard and ordered the product, because I wanted to create this Skin Care critique. It had been a "collagen set". I realize that many any antiaging Skin Care method promises to incorporate collagen because, I Have accomplished my research. And, since I have know a bit more about it compared to regular man, I know the fibers usually are made kind bovines, or cow hide.

Is it possible to make scatter-histogram plots in Maple13 like these

http://stackoverflow.com/questions/6508769/matplotlib-scatter-hist-with-stepfilled-histtype-in-histogram ?

I achieved the scatter-plot, but what about the additional histograms?

 

Sorry for making such a rude, big question. I have to solve these equations, but it's impossible ofcourse with my bad mathematics and even maple skills. Somebody help me pleaseㅠ_ㅠ

 

Differential equations

 

please write a program on matlab or maple for this dde

y'(x)=-y(x-pi/2)       0<x<=10

y(x)=sin(x)       x<=0

tau=pi/2

 

IT IS URGENT PLEASE

I'm currently having some difficulties in solving a system of differential equations numerically.

This is my code.

 

Dear friend! Hope you will be fine, I want to general matrix for m by m order. The file attached. I am waiting kind response.

can anybody help me? i want to check the consistency of my scheme. My equation is too long if i check manually, so i used maple 13 to simplify my equation. But it cannot simplify it because of length of output exceed limit 1000000

Hye, have a good day everyone..

can anyone know why I got this error? :(second_grade.mw

Error, (in dsolve/numeric/bvp/convertsys) unable to convert to an explicit first-order system


Here I have attached the file. thank you in advance :)

This might be a ridiculous question, but what is the easiest way to check the monotonicity of a function? I didn´t find anything helpful in the Maple Help, so maybe one of you could give me a nudge here :)

I find mapleform software   but I dont know how to use , and does anyone know another method to convert.  I know use 

> with(MmaTranslator);
> MmaToMaple();  

I can  automatically translated .nb files.  but this have  

Error, (in readline) file or directory does not exist
Error, (in readline) file or directory does not exist
Error, (in readline) file or directory does not exist
Error, (in readline) file or directory does not exist

another Error, missing operator or `;`

also I try to use 

> with(MmaTranslator);
> FromMmaNotebook(Mma_notebook_filename, options);

I still dont know how is works?  can you explains for me and show me some example  , here is my example files.plot.zip
