Well if we take the derivative we getQuote:

Can you finish from here?
By the way how is Corvallis? I miss it alot. I would kill for Tarn Tip Thai about now.
Hey jessicadowning.
Can you compute r'(t)? When are two vectors orthogonal? (Hint: it has something to do with something being 0)
Yeah, I got it from there, thanks so much!
And Corvallis is great, I'm loving it so far! (I'm a freshman, lol)
I haven't heard of Tarn Tip Thai, but it sounds good, I'll have to try it! :)
It is on Monroe on the North side of campus, it is inexpensive and they have good food. It is cash only so be prepared!Quote:
