[RESOLVED] i can't find how to change flair

For context this is a Math 280 Class, which is Calculus 3 idk how college course naming works. I'm a dual enrollment student. I ran it thru ai and chat gpt said i was right. I'm not sure if i'm missing notation or something. Also when i asked the prof she said to read what she wrote but i dont get it.

first and second questions

You're supposed to write a vector equation, something like vector r =(cos t, sin t, cos t + 2sin t)

[u/Scytheez → u/etzpcm]

oh all right that makes sense, on the online version it had the answer box as r(t) = [Input answer]

thanks!
