Question

r(t) = t^(6)i-6tj. What is r'(t)?

Answer 1

the derivative of r ...

Answer 2

yes, I know that but I keep getting the answer wrong when I'm actually solving for it.

Answer 3

what do you get when you try to solve?

Answer 4

the parts are pretty basic, so im not real sure what the difficulty is. If I could see your workings I prolly can determine the error

Answer 5

I'm not very good at calc so I'm trying to teach myself, sorry. I get 6t^(2)i-6j.

Answer 6

6-1 is not 2

Answer 7

so I just replace the 2 with 5 and it's right?

Answer 8

from what youve posted .. yes

r(t) = x(t) , y(t)

r'(t) = x'(t) , y'(t)

x = t^6
x' = 6t^5

y = -6t
y' = -6

Answer 9

alright thank you. much easier to understand than the explanation in the book.
