@electrokid can u help me with last two

how were you able to solve the first ones? You have to picture it and draw it first. Just a little bit of imagination gives the answer right away.

so you got the first three right? now you want a function that shows \[2[ \mathsf { {r}}(t)]\] So what was our original r(t)

r(t) = (tsint)i + (1cost)j so if it is 2[r(t)] = (2t2sint)i + (22cost)j is it correct?

@electrokid is this what you talking about? dw:1367589459350:dw i got this part but what abt rest part @FibonacciChick666 r(t) = (tsint)i + (1cost)j so if it is 2[r(t)] = (2t2sint)i + (22cost)j is it correct?

oh gotcha...so circumference is the vector function that models the behavior

r(t) is the vector function linear distance travelled is easier to analyse by considering curcumference distances

r(t) is the position of that small strip on the bigger loop with radius R "r" = radius of smaller loop (confusing symbol, so use another one maybe "a" find a relation between R and "a"

R = 2r....?

electrokid Group TitleBest ResponseYou've already chosen the best response.1
then what is the relation between "r(t)" and R?

wait r(t) = 2R...correct?

wow...how did u do that

electrokid Group TitleBest ResponseYou've already chosen the best response.1
never mind how. but do you see how the question works?

I'll let @FibonacciChick666 continue from here

ya circumference is equal to 2pi. It takes 6seconds approx for that circle to complete one revolution
