My bad! Thank you for correcting me and providing reference graphs, it's very appreciated. :)
I believe y = sin x and y = -1 intersect at (-π2/-1) in relation to the graph (Apologies for the late response!)
I think I understand, thank you for explaining! :)
I see, no wonder why I've been confused with these questions for a while, thanks again for your explanation, it really helps me!
This is great, thank you CPhill!
I understand now, thank you!
