If f (n)(0) = (n + 1)! for n = 0, 1, 2, , find the taylor series at a=0 for f.

Pie

Given that $f^{(n)}(0)=(n+1)!$ , we have for $f(x)$ the Taylor series expansion about 0 as

$f(x)=\displaystyle\sum_{n=0}^\infty\frac{(n+1)!}{n!}x^n=\sum_{n=0}^\infty(n+1)x^n$

Replace $n+1$ with $n$ , so that the series is equivalent to

$f(x)=\displaystyle\sum_{n=1}^\infty nx^{n-1}$

and notice that

$\displaystyle\frac{\mathrm d}{\mathrm dx}\sum_{n=0}^\infty x^n=\sum_{n=1}^\infty nx^{n-1}$

Recall that for $|x|$ , we have

$\displaystyle\sum_{n=0}^\infty x^n=\frac1{1-x}$

which means

$f(x)=\displaystyle\sum_{n=1}^\infty nx^{n-1}=\frac{\mathrm d}{\mathrm dx}\frac1{1-x}$
$\implies f(x)=\dfrac1{(1-x)^2}$

All help is much appreciated I really need it please

The two traingles, VSU and TSR are similar by SAS similarity criteria.

According to the diagram,
UT = TS
and
VR = SR

$\frac{ST}{SU} = \frac{ST}{ST + SU} \\ = \frac{ST}{2ST} = \frac{1}{2}$

Similarly for all sides the ratio must be same.
Applying this on the side required here,

$\frac{RT}{VU} = \frac{1}{2} \\ \\ \frac{p - 6}{p} = \frac{1}{2} \\ 2p - 12 = p \\ p = 12$

Therefore p = 12 units= UV .
