Dzokorora ndima iri pasi apa uye wozopindura mubvunzo unotevera mumutauro mumwechete se: Passage: Mhedzisiro iyi inoita kuti huwandu hwaAbel huwedzere, hunowanikwazve nekurega φ ((x) = exp ((−x). Chirevo chakajairika chinogona kuratidzwa nekubatanidza mazwi mumutsara pamusoro pe m uye kushandura chirevo kuita Riemann integral. Kune danho rekupedzisira, humbowo hunoenderana ne1 − 1 + 1 − 1 +... inoshandisa iyo yepakati kukosha theorem, asi pano munhu anoda yakasimba Lagrange chimiro cheiyo Taylor's theorem. Mubvunzo: Kuwedzerwa kwaAbel kunowanikwa sei?
nokurega φ(x) = exp(−x)
