draw the normal cos graph for the domain -3pi < x < pi and just shift the y axis to the left by pi units there u go

But also if the domain is like (0,2pi) then the shape of the graph will be different cause then it will only be a certain section of it and that’s also kinda dificult unless I use the long method which is so annoying
