irina1246 [14]

Answer:

Step-by-step explanation:

see pic below for quotient rule

\frac{(2x)'(x-1)-(2x)(x-1)'}{(x-1)^2}=\frac{2(x-1)-2x}{(x-1)^2}=\frac{2x-2-2x}{(x-1)^2}=-\frac{2}{(x-1)^2}

For the function given​ below, find a formula for the riemann sum obtained by dividing the interval​ [a,b] into n equal subinter
Nata [24]

We split [2, 4] into n subintervals of length \dfrac{4-2}n=\dfrac2n,

[2,4]=\left[2,2+\dfrac2n\right]\cup\left[2+\dfrac2n,2+\dfrac4n\right]\cup\left[2+\dfrac4n,2+\dfrac6n\right]\cup\cdots\cup\left[2+\dfrac{2(n-1)}n,4\right]

so that the right endpoints are given by the sequence

x_i=2+\dfrac{2i}n=\dfrac{2(n+i)}n

for 1\le i\le n. Then the Riemann sum approximating

\displaystyle\int_2^42x\,\mathrm dx

is

\displaystyle\sum_{i=1}^nf(x_i)\dfrac{4-2}n=\frac8{n^2}\sum_{i=1}^n(n+i)=\frac8{n^2}\left(n^2+\frac{n(n+1)}2\right)=\frac{12n+4}n

The integral is given exactly as n\to\infty, for which we get

\displaystyle\int_2^42x\,\mathrm dx=\lim_{n\to\infty}\frac{12n+4}n=12

To check: we have

\displaystyle\int_2^42x\,\mathrm dx=x^2\bigg|_2^4=4^2-2^2=16-4=12
