@k142.can you remember the period of this function that I asked yesterday?

OpenStudy (anonymous):

it was pi

OpenStudy (anonymous):

but one of members introduce this website to me https://www.desmos.com/calculator it drew the graph but i think period was pi/4.

OpenStudy (anonymous):

I don't think so. if pi/4 is to be the period then the function must repeat itself after x +pi/4 but it doesn't.
