Description
Describe the bug
The function sqrt(x) * sin((pi * x) / 2) is analyzed incorrectly by Windows Calculator. For example, it states that the function has no inflection points, when it has infinitely many.
Steps To Reproduce
- Open the calculator in Graphing mode.
- Enter the above equation and analyze it.
- Witness the erroneous information.
Expected behavior
Calculator should not claim that the function does not have any inflection points.
