EXAMPLE 2 Prove that 9ex is equal to the sum of its Maclaurin series. SOLUTION If f(x) = 9ex, then f (n + 1)(x) = for all n. If
amm1812

Answer:

To Prove: 9e^x is equal to the sum of its Maclaurin series.

Step-by-step explanation:

If f(x) = 9e^x, then f ^{(n + 1)(x)} =9e^x for all n. If d is any positive number and   |x| ≤ d, then |f^{(n + 1)(x)}| = 9e^x\leq  9e^d.

So Taylor's Inequality, with a = 0 and M = 9e^d, says that |R_n(x)| \leq \dfrac{9e^d}{(n+1)!} |x|^{n + 1} \:for\: |x| \leq  d.

Notice that the same constant M = 9e^d works for every value of n.

But, since lim_{n\to\infty}\dfrac{x^n}{n!} =0 $ for every real number x$,

We have lim_{n\to\infty} \dfrac{9e^d}{(n+1)!} |x|^{n + 1} =9e^d lim_{n\to\infty} \dfrac{|x|^{n + 1}}{(n+1)!} =0

It follows from the Squeeze Theorem that lim_{n\to\infty} |R_n(x)|=0 and therefore lim_{n\to\infty} R_n(x)=0 for all values of x.

THEOREM\\If f(x)=T_n(x)+R_n(x), $where $T_n $is the nth degree Taylor Polynomial of f at a and  $ lim_{n\to\infty} R_n(x)=0 \:  for \: |x-a|

By this theorem above, 9e^x is equal to the sum of its Maclaurin series, that is,

9e^x=\sum_{n=0}^{\infty}\frac{9x^n}{n!}  for all x.

ASPA PLEASE SOMEONE HELP ITS A TEST ,I NEED HELP ON NUMBER ONE , TWO , AND FOUR. I’ll GIVE YOU BRIANLEST PLS ASAP !!
natka813 [3]

1)

8.75 * 20 = 175

8 * 20 = 160

175 - 160 = 15

He'd make $15 more working at the amusement park.

2)

Semi-monthly means twice a month. So, her company is going from 2 to 4 pay periods.

3280 * 2 = 6560 (is what she makes per month)

6560/4 (because 4 weeks in a month) = 1640

OR (An alternative method.)

3280/2 = 1640

She'll be paid $1640 per week.

4)

105,000/12 (12 months in 1 year) = 8750 (He makes this per month)

8750 * 2 = 17500

He makes 17500 semi monthly

8750 /4 = 2187.5

2187.5 * 2 (because bi-weekly) = 4375

He makes 4375 bi-weekly

8750/4 = 2187.5

He makes 2187.5 every week

Dont forget to add the dollar signs. I didnt add them, but you need to. If you need me to add them I can.
