Dear Desmos Community,

I have tried my first attempts at including the correct sink the activity Trigonometrische Schaubilder: Die Periodenlänge • Activity Builder by Desmos (based on activity Trigonometric Graphing: Introduction to Amplitude and Vertical Shift • Activity Builder by Desmos)

I tried it the following way, which unfortunately does not seem to work:

correct: (p0.numericValue=6.28319 or p0.latex=`2\pi`

) and graph0.number(“d”)<0.1

Could you maybe point me to where my mistake is? Thanks a lot in advance!
