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.(adsbygoogle = window.adsbygoogle || []).push({});

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 or equal to) for all t.

2.a) For x and y real, solve the equation iy/(1+ix) - (3y + 5i)/(3x + y) = 0

b) Z = (1 + iw)/(1 + iw - w^2). Assume w > (greater than or equal to). Find and then sketh |Z| and arg Z as functions of w.

I really need help with these asap. Thanks in advance.
