Matematika 2 Pegi Ushtrime Te Zgjidhura 💯

( y(x) = \frac{1}{2} + C e^{-x^2} ) Ushtrimi 3: Seriali (kriteri i raportit) Studioni konvergjencën e serisë: [ \sum_{n=1}^{\infty} \frac{n!}{n^n} ]

Përdorim kriterin e raportit: ( a_n = \frac{n!}{n^n} ) [ \frac{a_{n+1}}{a_n} = \frac{(n+1)!}{(n+1)^{n+1}} \cdot \frac{n^n}{n!} = \frac{n+1}{(n+1)^{n+1}} \cdot n^n = \frac{n^n}{(n+1)^n} = \frac{1}{\left(1+\frac{1}{n}\right)^n} ] Kur ( n \to \infty ), ( \left(1+\frac{1}{n}\right)^n \to e ), pra ( \frac{a_{n+1}}{a_n} \to \frac{1}{e} \approx 0.368 < 1 ). Rrjedhimisht, seria konvergjon absolutisht. matematika 2 pegi ushtrime te zgjidhura

Konvergjon Ushtrimi 4: Integral i dyfishtë (koordinata polare) Llogaritni sipërfaqen e rrethit ( x^2 + y^2 \leq 4 ). ( y(x) = \frac{1}{2} + C e^{-x^2} )
