高一數學週期函數的週期求法
比如說f(x)=f(x+1)+f(x-1),求函數週期.書上說答案是6,但這類題目我總沒思路,高手請指教一下求週期的方法
f(x)=f(x+1)+f(x-1)把x+1看成x有
f(x+1)=f(x+2)+f(x)
兩式相加
f(x+2)= - f(x-1)
f(x-1)= - f(x-4)
則f(x+2)=f(x-4)
也就是f(x)=f(x+6)
現在進行時、一般現在時、一般將來時、一般過去時的肯定句、否定句、疑問句.最好是表格的形式.
我建議不要把他們分開來記憶,
肯定句變否定句:首先找謂語動詞1、動詞為BE,WILL,CAN時,直接在其後加NOT .2動詞為實義動詞時,分時態A一般現在時,主語是第三人稱單數的,一律在動詞前加DOESN'T,動詞改為動詞原形,當主語是除了第三人稱單數外的其他人稱時,則在動詞前加DON'T .B時態為一般過去時時,一律在動詞前加DIDN'T,動詞用原形.
注意:1遇到SOME要改為ANY
肯定句變一般疑問句,方法和變否定句的一樣,同樣是先分動詞和時態的.
動詞分為1 BE,CAN,WILL,直接把這類動詞提前在句首2謂語動詞是實義動詞時就要分時態A一般現在時時,先分清人稱.主語是第三人稱單數時,句首用DOES提問,謂語動詞改為動詞原形,除了第三人稱單數的其他人稱時用DO.B一般過去時,句首一律用DID提問,謂語動詞改為動詞原形
注意:肯定句中有some改為any,my,our改為your,I,WE改為you;最後就是標點符號要改問號
如何求函數週期,思路是什麼?應該如何想這個問題
補充兩個例題:定義在R上的奇函數f(x)對任意x滿足f(x-)=f(4-x),且f(x)=x,x∈(0,2/3],則f(2013)-f(2012)=
已知函數y=f(x)是R上的偶函數,對於x∈R都有f(x+6)=f(x)+f(3)成立,當x1,x2∈[0,3],且x1≠x2時,都有{f(x1)-f(x2)}/(x1-x2)>0,應該從哪裡找突破口
抽象函數先賦值,第二題:令x等於-3時求f(3)=0,則有f(x+6)=f(x),所以f(x)為週期是6的偶函數,由於當x1,x2∈[0,3],且x1≠x2時,({fx1)-f(x2)}/(x1-x2)>0所以f(x)0,3]為增,且其為偶函數,則f(x)在[-3,3]先减後增,6為週期….

高中數學函數週期的求法
已知定義在R上的函數f(x)對任意的x滿足f(x+1)=-f(x)求次函數的週期.
f(x+1)=-f(x)
f(x+2)=-f(x+1)
f(x+2)=f(x)
週期2
一般的函數,用公式2π÷ω。如遇到特殊的如sinax(a>0)絕對值,這時最小正週期减半,為π÷a。一般更特殊的,按照週期减半法(自創的),即從2π開始試,如果符合,就將週期减半為π,再檢驗,如果還符合,以此類推,再减半,知道不符合才停止,那麼符合的最小週期即為最小正週期。如果這樣還求不出來,那我也沒辦法了。考試一般不回出太麻煩的,用公式就可以了。望採納。

令x=x+1
f(x+2)=f(x+1+1)=-f(x+1)=f(x)
週期為2

很簡單的週期函數
f(派/3+x)=-f(x)的週期是派/3嗎?若不是,應該是什麼?
不是.
f(x)=-f(派/3+x)
f(派/3+x)=-f(2派/3+x)
f(x)=f(2派/3+x)
週期是2派/3
用現在進行時,一般將來時,一般現在時,一般過去時各造一句肯定句,否定句,一般疑問句,特殊疑問句
