Find the Taylor series for f(x) centered at the given value of a. [Assume that f has a power series expansion. Do not show that
juin [17]

Answer:

The Taylor series of f(x) around the point a, can be written as:

f(x) = f(a) + \frac{df}{dx}(a)*(x -a) + (1/2!)\frac{d^2f}{dx^2}(a)*(x - a)^2 + .....

Here we have:

f(x) = 4*cos(x)

a = 7*pi

then, let's calculate each part:

f(a) = 4*cos(7*pi) = -4

df/dx = -4*sin(x)

(df/dx)(a) = -4*sin(7*pi) = 0

(d^2f)/(dx^2) = -4*cos(x)

(d^2f)/(dx^2)(a) = -4*cos(7*pi) = 4

Here we already can see two things:

the odd derivatives will have a sin(x) function that is zero when evaluated in x = 7*pi, and we also can see that the sign will alternate between consecutive terms.

so we only will work with the even powers of the series:

f(x) = -4 + (1/2!)*4*(x - 7*pi)^2 - (1/4!)*4*(x - 7*pi)^4 + ....

So we can write it as:

f(x) = ∑fₙ

Such that the n-th term can written as:

fn = (-1)^{2n + 1}*4*(x - 7*pi)^{2n}

If you have a 5 letters A,B,C,D,E and you can put them in any order how many ways can you place them
IceJOKER [234]

The first letter can be any one of 5.  For each of those . . .
The second letter can be any one of the remaining 4.  For each of those . . .
The third letter can be any one of the remaining 3.  For each of those . . .
The fourth letter can be any one of the remaining 2.  For either of those . . .
The fifth letter is the last remaining one.

  Total number of possibilities = (5 x 4 x 3 x 2 x 1)  = 

                                                          <em> 120 ways</em> to line them up.

Now, may I say that being a hater of school is not something that
makes you cool.  Maybe it does make you one of the crowd, but life
is not a war between you and school.  School is simply something that
a lot of grown-ups spend a lot of money on, and a lot of teachers spend
their whole life on, to make sure that a lot of kids won't go through <em><u>their</u></em>
whole life stupid.  You can learn everything you ever want to know there,
and it's all free.  That's a pretty good deal.

Answer:

41.13 sq m

Step-by-step explanation:

area of square = 4² = 16

there are two quarter-circles which equals one semicircle

area of semi-circle is πr²/2

A = 4²π/2 = 8π = 25.13

add together: 16 + 25.13 = 41.13
