煩請各位大大撥冗來幫我解決著個問題好嗎?急著要破解它!
那麼不多說,題目如下:
Find the transition matrix representing the change of coordinate on P3,
where P3 denotes the set of all polynomials of degree less than 3,
from the basis α=[1,x,x^2] to the basis β=[1,1+x,1+x+x^2], also
find the coordinate of f=a+bx+cx^2 relative to basisβ.
答案:
transition matrix T is [(1,0,0)^t,(-1,1,0)^t,(0,-1,1)^t]
the coordinate of f=a+bx+cx^2 relative to basisβ is
→
fβ=[(a-b)^t,(b-c)^t,(c)]
=T[a,b,c]^t
我有疑問的是,我算出來的T與解答不一樣耶!在題目敘述中有甚麼特別的提示嗎?
還有該如何解?
另外第二個問題的答案也可以請各位大大幫我看一下嗎?
先謝謝嚕!
