Imisebenzi okuthi, ngokwahlukana okubaluliwe kwe f(x), yenze isamba

(f(x)) = f(a) + f(a + 1) + f(a + 2) + ⋯ + f(b).

Isifaki se-syntax Yesibonisi Semvelo yilesi (f(x)), kuyilapho isifaki se-syntax Yesibonisi Somugqa kuyilesi ∑(f(x); a; b).

U-a no-b yizinombolo ezingabalulwa phakathi nokwahlukana kuka -1 × 1010 < a ≦ b < 1 × 1010.

Isibonelo: (x + 1) = 20

Okulandelayo ngeke kusetshenziswe ku-f(x): Pol, Rec, ÷R. Okulandelayo ngeke kusetshenziswe kulokhu f(x), a, noma b: ∫, d/dx, Σ.
