CasCalc is an independent project run by Cody Wang. Questions, bug reports and suggestions are all welcome, and every message is read.
I usually reply within a few days.
Reporting a wrong answer or a bug
If CasCalc gives a result that looks wrong, please include:
- The exact input you typed, for example
factor(x^4 - 16) - The answer CasCalc showed, and the answer you expected
- Your browser and device, for example Chrome on Windows or Safari on iPhone
A screenshot helps too. Reports like this make the calculator more accurate for everyone.
Feature requests
Would a new function, graph type or math guide help you? Tell me what you are studying and what you need. Many of the current features came from requests like these.
