Sumas: De Riemann Ejercicios Resueltos Pdf

[ L_n = \frac2n [4n + 3(n-1)] = \frac2n (7n - 3) = 14 - \frac6n ]

Sum: (\sum_i=0^n-1 4 = 4n,\ \sum_i=0^n-1 \frac6in = \frac6n \cdot \fracn(n-1)2 = 3(n-1))

[ \int_a^b f(x) , dx = \lim_n \to \infty \sum_i=1^n f(x_i^*) \Delta x ] sumas de riemann ejercicios resueltos pdf

Better: (R_n = \frac2n \sum_i=1^n (4 + \frac6in) = \frac2n[4n + \frac6n\cdot \fracn(n+1)2] = \frac2n[4n + 3(n+1)] = 14 + \frac6n)

Similarly, (R_n = 14 + \frac6n) (check: (R_n = L_n + \Delta x (f(b)-f(a)))? (f(b)-f(a)=6,\ \Delta x \cdot 6 = \frac12n), but careful – compute:) [ L_n = \frac2n [4n + 3(n-1)] =

Exact: (\int_0^\pi \sin x , dx = 2). So (M_4 \approx 1.896) (error (\approx 0.104)). Express (\lim_n \to \infty \frac1n \sum_i=1^n \left(1 + \fracin\right)^3) as an integral.

Note: (\sin(5\pi/8) = \sin(3\pi/8),\ \sin(7\pi/8) = \sin(\pi/8)) Express (\lim_n \to \infty \frac1n \sum_i=1^n \left(1 +

: (\int_0^2 x^2 dx = \fracx^33 \Big|_0^2 = \frac83 \approx 2.6667)
