试题 :
1.y''-2y'+2y=sin(t)
Please list the formula of Runge-Kutta method of order 4
for this second order differential equation.
Assume y(0)=-0.6 y'(0)=-0.4.
2.y(t)=2000+1000*exp(t)-3000.
Please find the range of step-size that
the estimation result of Euler method would be stable.
3.Approximate function of natural cubic spline
given the following data:
x │ f(x)
───────
8.3 │ 1.547056
│
8.6 │ 1.478362
│
│
4.Evaluate the following integration with
Simpson's method with step-size=0.25 :
1
∫ x^2 dx = ?
0
5.Use Newton method to find p2
given f(x)=x^2-6 and p0=1.

1F:推 tom128 :补一下101之期中考古,老师今年的方向有点不同 04/20 16:03
2F:→ tom128 :除了基本运算(Newton method、Neville method)之外 04/20 16:03
3F:→ tom128 :老师还加考了两大题的证明,分别为以Taylor证Simpson 04/20 16:04
4F:→ tom128 :1/3method,和以Lagrange证three-pts formula 04/20 16:06
5F:→ tom128 :不过今年老师提早了一周考试,所以范围缩小了一些 04/20 16:06
6F:→ tom128 :提供大家参考啦! 04/20 16:07
