I\'m trying to simplify some symbolic equations. >> syms x; >> simplify(sqrt(x^2)/x) ans = (x^2)^(1/2)/x
For example, I\'d like to define x and y 开发者_运维百科as non-commutative, and a and b as commutative (as usual). In other words,
We know 1+2+...+n is equal to n(n+1)/2. But can we get the same result programatically if we don\'t know it in 开发者_C百科advance?
MuPAD\'s text output is ridiculously small for me to read, and although every time I adjust the size, it does not seem to save my preferences. Is there any way to set MuPAD\'s text size so that it sta
My problem: symbolic ex开发者_开发知识库pression manipulation. A symbolic expression is built starting from integer constants and variable with the help of operators like +, -, *, /, min,max. More ex

Is there a (matlab) symsum equivalent in R? Thank y开发者_运维技巧ou!R doesn\'t do symbolic maths by itself but you can link to yacas, which does (via the Ryacas package).
I have some functions set up like this: f(x):=1-2**-x$ g(y):=integrate(f(x), x, 0, y)$ and evaluated them:
I\'ve got two sequences with variable boundaries like > a:=Sum(x(i),i=n..m); > b:=Sum(x(i),i=开发者_JS百科n-1..m+1);
I\'m trying to perform the following integral in Maple: simplify开发者_如何转开发(int(a*x^2*e^(-a*x^2), x = -infinity .. infinity))
