(1)
Using the iteration formila
Xn+1=(22Xn+50)^1/4 and X0=3.5
find a root of the equation x^4-22x-50=0 TO 4sf
(2) During the boost stage of a rocket launch, the height h in metres, after t seconds is given h=3t^4-2t^3+15t2

B.Find the acceleration of the rocket at t=3 secs作者: Naozumi 時間: 10-3-30 07:58 AM
第1題,純粹用條iteration formula照計喎,用excel計一計啦
第2題 v = dh/dt 再代 t = 3
a = second derivative of h at t = 3作者: defg105 時間: 10-4-11 03:38 AM
