[sage-support] Extended Operations on Symbols
I am writing a calculator for various 'q' quantities, and often find that I need to manipulate symbols more flexibly. For example, I have to deal with the expression ( q + q^(-1) ) ^ (1/2) -- (*) But currently I could not find any way to achieve this. A naive attempt gives a failure: sage: q = Frac(ZZ['q']).gen() sage: q ^ (1/2) ---> ValueError: not a 2nd power sage: power(q, 1/2) NotImplementedError: non-integral exponents not supported Leave alone the expression I need! Indeed, one might have to define a larger parent for the expression (*) to live in. So this might require implementing a new algebraic structure. If that's the case, I'm willing to write it. The problem is that implementing a new structure seems a bit complicated to me.. I might take some time, and need some guides. Thank you so much! PS. Weirdly enough, exp(sin(q)) is already implemented as in the class . Perhaps what I need might not be too hard to implement? -- You received this message because you are subscribed to the Google Groups "sage-support" group.

Woah! Thank you so much! p.s. I said it's naive because I have no better idea.. perhaps there's a better wording.

[sage-support] Is log_html() deprecated?
I'd like to log my entire session in sage into a file. The best solution I found is to use log_html(). http://doc.sagemath.org/html/en/reference/misc/sage/misc/log.html But the functions seems deprecated, and the document about it I've found is more than a decade. sage: log_html() --- NameError Traceback (most recent call last) in > 1 log_html() NameError: name 'log_html' is not defined sage: log_html --- NameError Traceback (most recent call last) in > 1 log_html NameError: name 'log_html' is not defined -- You received this message because you are subscribed to the Google Groups "sage-support" group.

Apology for more stupid questions. I imported and it loaded, but still failed: sage: from sage.misc.log import log_html sage: log_html sage: log_html() --- AttributeErrorTraceback (most recent call last) in > 1 log_html() /usr/lib/python3.8/site-packages/sage/misc/log.py in __init__(self, dir, debug, viewer) 97 self._dir = dir 98 self._filename = os.path.join(dir, self._filename()) ---> 99 self._output = __IPYTHON__.output_hist 100 self._input = __IPYTHON__.input_hist_raw 101 self._text = '' AttributeError: 'bool' object has no attribute 'output_hist' sage: -- You received this message because you are subscribed to the Google Groups "sage-support" group.
