2 Exponents

3 Multiplication and Division (from left to right)

4 Addition and Subtraction (from left to right)

(7+41) = 48

48 ÷ 2 = 24

24 -15 = 9

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

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

Two brothers are saving money to buy tickets to a concert. their combined saving is $55 one brother has $15 more than the other.

Vladimir [108]

Brother one: x

Brother two: x + 15

---

Make them add up to 55 in an equation.

x + (x + 15) = 55

Combine like terms.

2x + 15 = 55

Subtract 15 from both sides.

2x = 40

Divide both sides by 2.

x = 20

Plug 20 for x into brother two.

(20) + 15 = 35

Brother one has saved $20, brother two has saved $35.

There are 11 women and 9 men in a certain club. If the club is to select a committee of 2 women and 2 men, how many different su

Sunny_sXe [5.5K]

We can tell it’s not a permutation because it’s picking two people. Order doesn’t matter.

The number of total possible groups of men is 9 C 2 = 9!/((9-2)!(2!)) = 36

The number of total possible groups of women is 11 C 2 = 11!/((11-2)!(2!)) = 55

55 * 36 = 1980 different groups in the committee
