i've worked the first one out but still stuck with what to do on the other ones?
can anyone tell me if this is right for question 1??
a)
. . .dy/dt .= .-2sin(2t)
. . .dx/dt .= .2 + 2cos(2t)
. . . . . . . . .dy/dt . . . . . . .-2 sin(2t) . . . . . - 2 sin(t)cos(t) . . . . - sin(t)...
Hi guys I'm trying to prepare for an exam coming up (that time again :( ) and I've found a few problems in my textbook I don't really know how to do. I really need to do well on this so if anyone could help me out i'd really appreciate it! :D

A curve has parametric equations: x...
Hi I've been working on my assignment for ages and am down to the last two questions (finally) which I've been working on for ages and can't work out.
1. For g(t) = 2sint+cos2t over 0 <(equal to or greater than) x < (equal to or greater than) 4pi
show that -3 < g(t) < 3/2 (< greater than...
