[理工] [線代] 線性映射
E={u1,u2,u3} , F= {b1,b2}
u1=(1,0,-1)^t u2=(1,2,1)^t u3=(-1,1,1)^t
b1=(1,-1)^t b2=(2,-1)^t
L(X)=(X1+X2,X1-X3)^t from R3 to R2
find representing L with respect to the order base E and F
可以這樣解嗎
[1 2]^-1 [1 1 0] [ 1 1 1]
[-1 -1] [1 0 -1] [ 0 2 1]
[-1 1 1]

When we toss a coin , we obtain either head or tail. Now we toss a coin 5
times. There are 2^5 possible outcomes. How many of them contain no two
consecutive heads?

抄錯了，難怪都算錯
[1 2]^-1 [1 1 0] [ 1 1 -1]
[-1 -1] [1 0 -1] [ 0 2 1]
[-1 1 1]
[-5 -3 4]
[ 3 3 -2]
