[問題] 應考資格、各種國考疑難雜症等,以有正確作法、答案者為主
(不包括書裡的疑問)。若問題如人生規劃、讀書計畫等,無一
定作法、答案者,請用閒聊選項。
請問今年工程數學第17題:
y'+y = y^2 的解為? (A)1+ce^x(B)1/(1+ce^x)(C)1-ce^x(D)1/(1-ce^x)
考選部公布的答案為 (B) y=1/(1+ce^x)。
但其實這題C為常數,且沒有給定任何初始條件,那這樣答案(D) y=1/(1-ce^x)
也可以呀。實際帶回題目也是驗證對的,這樣我如果想申請疑義的話還要甚麼
佐證資料呢~~?
另外想請問各位大大,題目有瑕疵也能申請疑義嗎~~像是工數第三題的第三小題~~?
