Then we can expand it in a Taylor series and take a few terms of the series to approximate it. Can Sagemath do this? If yes, how?cdelvMon, 20 Dec 2021 03:37:09 +0100https://ask.sagemath.org/question/60367/Error in integralhttps://ask.sagemath.org/question/53172/error-in-integral/I've got this error on the second integral. I put the code on wxMaxima and returned sucessfull. On wxMaxima, raise a question "z is positive, negative or zero?", also on sage, but on sage I can't answer that. How can I correct this?
```x,y,z = var("x y z")```
```function = x*e^(-y)```
``` integral(function,y,0,ln(x)).integral(x,0,2*z) ```gabrielromao5Tue, 25 Aug 2020 15:50:58 +0200https://ask.sagemath.org/question/53172/Integration and differentiation symbolshttps://ask.sagemath.org/question/36441/integration-and-differentiation-symbols/I have seen this in the examples but it doesn't appear to be very easy unless I am totally missing something. It is important that the proper symbology be used in presentation form to show the integration symbol and or differentiation symbol. But can't seem to find any way of doing it . This should be straight forward like show(integral()) and it puts the integral symbol on the screen especially in showing symbolic calculations.
How do you get the symbols on the screen? NT4MAXIMUSDThu, 02 Feb 2017 14:15:53 +0100https://ask.sagemath.org/question/36441/Calculating Integralhttps://ask.sagemath.org/question/8048/calculating-integral/f(x) = e**(-x) * log(x+1);<br>
uu = integral(f, (x, 0, oo));<br>

why this dont work?SagudWed, 06 Apr 2011 18:49:23 +0200https://ask.sagemath.org/question/8048/
