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! -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 111.248.17.64
