Thepa ea Letoto la Lijiometri

Tatellano ea jeometri e na le litšobotsi tse 'maloa tsa bohlokoa tse etsang hore e be molemo haholo lits'ebetsong tse fapaneng. Tse ling tsa tsena ke:

1. Ho Atisa ho sa Feleng: Mantswe a mabedi a latellanang ka tatellano ya jeometri a na le karolelano e sa fetoheng.
2. Thepa e Iphetolang: Lentswe ka leng le ka fumanwa ka ho atisa lentswe le fetileng ka karolelano e tlwaelehileng.
3. Exponential: Sebopeho se akaretsang sa mareo a tatellanong ya jeometri se bontsha kgolo ya exponential (haeba \(r > 1\)) kapa ho bola ha exponential (haeba \(0 < r < 1\)).

Kakaretso ea Mantsoe a Pele a N Karolo e 'ngoe ea bohlokoa ea tatellano ea jeometri ke bokhoni ba ho bala kakaretso ea mantsoe a pele a tatellano. Haeba re batla ho tseba kakaretso ea mantsoe a pele a n a tatellano ea jeometri, re ka sebelisa foromo e latelang: \[ S_n = a \frac{r^n - 1}{r - 1} \] bakeng sa \( r \neq 1 \). Haeba \( r = 1 \), joale tatellano ha e fetohe 'me kakaretso ea mantsoe a pele a bonolo a n ke \( S_n = n \cdot a \). Bopaki: A re re \( S_n \) e be kakaretso ea mantsoe a pele a n a tatellano ea jeometri: \[ S_n = a + ar + ar^2 + ar^3 + \cdots + ar^{n-1} \] Atisa mahlakore ka bobeli ka karolelano e tloaelehileng, \( r \): \[ rS_n = ar + ar^2 + ar^3 + \cdots + ar^n \] Joale, tlosa \( S_n \): \[ S_n - rS_n = a - ar^n \] \[ S_n (1 - r) = a(1 - r^n) \] Ebe, \[ S_n = a \frac{1 - r^n}{1 - r}, \] kapa \[ S_n = a \frac{r^n - 1}{r - 1} \] bakeng sa \( r \neq 1 \). Tšebeliso ea Litatelano tsa Jiometri 1. Lichelete: E 'ngoe ea lits'ebetso tse tloaelehileng tsa tatelano ea jeometri ke licheleteng, haholo-holo ho baleng phaello e kopaneng. Haeba motho a boloka ka phaello e baloang selemo le selemo, boleng ba ho qetela ba polokelo bo ka fumanoa ka mokhoa o ts'oanang le tatelano ea jeometri. 2.
