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

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

An amusement park sells adult tickets and children’s tickets, with adults tickets costing $5 and children’s tickets costing $3.

Katarina [22]

Answer:

Nine

Step-by-step explanation:

3 dollars for children tickets : x

5 dollars for adult tickets: y

Equation is:

3x+5y=57

Where 57 is the total amount spent

x+y=15

where 15 is the total number of tickets bought

3x+5y=57

5(x+y)=5(15)

___________________

3x+5y=57

5x+5y=75

minus the equations top to bottom=

-2x= -18

x= -18/(-2)

x=9

He bought a total of 9 children tickets
