system of equations 2
1234567890 我淆淆地= =a係咪直接put x=y for all x = =? x=y is a solution 者
又唔係all solutions 個2個function degree 係唔係乜都無所謂?_?

yes
1234567890 f(x)+g(y)=c 同 g(x)+f(y)=c 有咩分別@@?
佢地都係R→R function入面個domain ge分別
當然 你put左x=y就冇左呢個分別啦 簡單d
左邊put x=y
=0=右邊
補番句 if the solution exist
寫答案 a part收工= =
扣分就扣啦
反正諗唔到第個方法
佢又唔係linearly independent 本帖最後由 bearwing 於 21-6-2009 19:04 編輯
Define h(x)=f(x)-g(x)
If x=y
h(x)=h(y)
Hence the desired result.
Anyone try part b)? i think that's easier
