f(x)=x3-15x+c => f'(x)=3x2-15 在[-2, 2]內 f'(x)<0, so, f(x)遞減 故f(x)=0在[-2, 2]內最多只有一根 2008-01-03 19:00:50 補充： 所以說"最多"只有一根啊 ! 2008-01-03 20:14:31 補充： 可能在[-2, 2]內沒有實根!
先寫出第一題: 第一步: >> x1 = 0:0.1:0.6; % 0~0.6之間, 間隔0.1 >> f1 = cos(x1); %求出此線段之cos(x) >> x2 = 0:0.1:0.9; % 同上 >> f2 = cos(x2); % 同上 第二步: >> p1 = polyfit(x1,f1,4); % 找出內插多項式(其中4為使用5次多項式) >> f1_interp = polyval(p1,0.45); % 內插出0.45時的cos(x)值 >> p2...
