Best ResponseYou've already chosen the best response.1yeah still wrong \[\hat r t=<t+sin\frac12 \pi t,t+cos \frac12 \pi t>\]

Best ResponseYou've already chosen the best response.3\[t\vec r=<t+\sin\frac12 \pi t,t+\cos \frac12 \pi t>\]makes more sense

Best ResponseYou've already chosen the best response.3\[t\vec r=\langle t+\sin(\frac\pi2 t),t+\cos(\frac\pi2t)\rangle\]is this right is 1/2pit the argument of the trig function

Best ResponseYou've already chosen the best response.3and is t being multiplied by r on the left? this notation is confuzzling me

Best ResponseYou've already chosen the best response.3\[\vec r(t)=\langle t+\sin(\frac\pi2 t),t+\cos(\frac\pi2t)\rangle\]correct?

Best ResponseYou've already chosen the best response.3\[\vec r(t)=\langle x(t),y(t)\rangle\]so that implies that\[\vec r(t)=\langle t+\sin(\frac\pi2 t),t+\cos(\frac\pi2t)\rangle\]leads to\[x(t)=t+\sin(\frac\pi2t)\]\[y(t)=t+\cos(\frac\pi2t)\]

Best ResponseYou've already chosen the best response.3so it is just a matter of identifying the components

Best ResponseYou've already chosen the best response.1yep. It makes sense now. I initially wrote it without putting a comma in, and i forgot a "t" somewhere which made it more confusing. But yeah that makes perfect sense.

Best ResponseYou've already chosen the best response.3no prob, this is not one of the harder parts of vector calculus fortunately :)
