求二題詳解！！！

2.設為實數,已知lim 解 2. 解 x→0 √x+k² + K x 力 1 4 , 試求k之值。

求問兩題詳解！！ 為何是非那題不正確？

觀念是非題:正確請填,錯誤請填×,每題2分,共10 ) 1. 已知lim f(x) x→1 g(x) -- 1 , 則lim f(x)=1且limg(x)=2。 2 x→1 x→1 ( O ) 2. 已知多項式函數f(x)f(2)=5,則limf(x)=5 x→2 X)3. 設f(x)三因為高斯函數,則lim[x]不存在。

想問這題要怎麼證明 不知道要怎麼證明單調跟有界

No. Date nic For use every "I nεN, let an = 1 + 1/2 + 1/3 + 111 + 1/1/1 - \n (n) Monotonic Sequence Theorem" to prove the sequence {an{m² converges.

不懂為什麼這樣計算 ∠JFE+ ∠DIC= ∠FED+ ∠EDI-180？為什麼

Bet (C)16 如右圖,已知ABCDE 為正五邊形,DEFGHI為正六邊形,過 P177 F點作//cd,則<JFE= ? J F AE 【範例] (5-2) X180° 11 A 34° 16 正五邊形任一內角=- B =108° DH 5 (B) 35° (6-2) X180° CI 正六邊形任一內角=- -=120° 6 (C) 36° (D) 37° LCDI 360°-108-120°=132° CD-DE=DILDIC=(180°-132°) +2=24° XLJFE+LDIC=LFED+LEDI-180° LJFE=120° +120°-180°-24°=36°

求解

請問第17題怎麼解

17 如右圖,AB || DE, BC || EF,且∠ABE=40°,∠CBE=85°, 則∠DEF是多少度? 85 B E

在太空中丟一個球出去，這個球會遵守牛頓運動定律嗎？

這題好怪 一直把最小值算成4⋯ 求這題過程

f(x) = |x - 1| + |x + 3,求x之範圍,使f(x)有最小值,並求它的最小值。 答:1≤x≤3,2
