a) xp = 3et + \(\frac{t}{2}\) (cost – 2 sint )
b) xp = 3tet + \(\frac{1}{2}\) (cost + sint )
c) xp = 3tet + \(\frac{t}{3}\) (4cost + 2sint )
d) xp = 3et + \(\frac{1}{2}\) (cost – sint )
b) xp = 3tet + \(\frac{1}{2}\) (cost + sint )
c) xp = 3tet + \(\frac{t}{3}\) (4cost + 2sint )
d) xp = 3et + \(\frac{1}{2}\) (cost – sint )
