Best ResponseYou've already chosen the best response.1how 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.

Best ResponseYou've already chosen the best response.0so you got the first three right? now you want a function that shows \[2[ \mathsf { {r}}(t)]\] So what was our original r(t)

Best ResponseYou've already chosen the best response.0r(t) = (tsint)i + (1cost)j so if it is 2[r(t)] = (2t2sint)i + (22cost)j is it correct?

Best ResponseYou've already chosen the best response.0@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?

Best ResponseYou've already chosen the best response.1dw:1367594594073:dw r(t) is the position vector of that small balck strip

Best ResponseYou've already chosen the best response.0oh gotcha...so circumference is the vector function that models the behavior

Best ResponseYou've already chosen the best response.1r(t) is the vector function linear distance travelled is easier to analyse by considering curcumference distances

Best ResponseYou've already chosen the best response.1r(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"

Best ResponseYou've already chosen the best response.0R = 2r....?

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

Best ResponseYou've already chosen the best response.0r(t) = 4piR...?

Best ResponseYou've already chosen the best response.0wait r(t) = 2R...correct?

Best ResponseYou've already chosen the best response.0wow...how did u do that

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

Best ResponseYou've already chosen the best response.1I'll let @FibonacciChick666 continue from here

Best ResponseYou've already chosen the best response.0ya circumference is equal to 2pi. It takes 6seconds approx for that circle to complete one revolution
