→ Narcissuss:二次式嗎？ 04/05 05:54
這份考卷的最後一題
In R2, there are two sets of coordinate systems, represented by two distinct
bases: (x1,y1) and (x2,y2). If the equations of the same ellipse represented
by the two distinct bases are discried as follows, respectively:
2(x1)^2 - 4(x1)(y1) + 5(y1)^2 - 36 = 0
(x2)^2 + 6(y2)^2 - 36 = 0
Please find the transformation matrix between these two coordinate systems:
(x1,y1) and (x2,y2).
有高手會這一題嗎? 請教教我吧
謝謝

是我線代沒唸熟還是這題真的太難了?
