Classify the following expression by degree and term:
PIT_PIT [208]

Answer:

2nd degree trinomial

Step-by-step explanation:

4x^2 + 3xy + 12yz

Degree of the polynomial is the highest degree of each term

We are given with three terms.

To find the degree of each term , add the exponents

4x^2 , degree 2

3xy, degree 2

12yx, degree 2

The degree of the given polynomial is 2

So its a 2nd degree trinomial

Find the Fourier series of f on the given interval. f(x) = 1, ?7 < x < 0 1 + x, 0 ? x < 7
Zolol [24]
f(x)=\begin{cases}1&\text{for }-7

The Fourier series expansion of f(x) is given by

\dfrac{a_0}2+\displaystyle\sum_{n\ge1}a_n\cos\frac{n\pi x}7+\sum_{n\ge1}b_n\sin\frac{n\pi x}7

where we have

a_0=\displaystyle\frac17\int_{-7}^7f(x)\,\mathrm dx
a_0=\displaystyle\frac17\left(\int_{-7}^0\mathrm dx+\int_0^7(1+x)\,\mathrm dx\right)
a_0=\dfrac{7+\frac{63}2}7=\dfrac{11}2

The coefficients of the cosine series are

a_n=\displaystyle\frac17\int_{-7}^7f(x)\cos\dfrac{n\pi x}7\,\mathrm dx
a_n=\displaystyle\frac17\left(\int_{-7}^0\cos\frac{n\pi x}7\,\mathrm dx+\int_0^7(1+x)\cos\frac{n\pi x}7\,\mathrm dx\right)
a_n=\dfrac{9\sin n\pi}{n\pi}+\dfrac{7\cos n\pi-7}{n^2\pi^2}
a_n=\dfrac{7(-1)^n-7}{n^2\pi^2}

When n is even, the numerator vanishes, so we consider odd n, i.e. n=2k-1 for k\in\mathbb N, leaving us with

a_n=a_{2k-1}=\dfrac{7(-1)-7}{(2k-1)^2\pi^2}=-\dfrac{14}{(2k-1)^2\pi^2}

Meanwhile, the coefficients of the sine series are given by

b_n=\displaystyle\frac17\int_{-7}^7f(x)\sin\dfrac{n\pi x}7\,\mathrm dx
b_n=\displaystyle\frac17\left(\int_{-7}^0\sin\dfrac{n\pi x}7\,\mathrm dx+\int_0^7(1+x)\sin\dfrac{n\pi x}7\,\mathrm dx\right)
b_n=-\dfrac{7\cos n\pi}{n\pi}+\dfrac{7\sin n\pi}{n^2\pi^2}
b_n=\dfrac{7(-1)^{n+1}}{n\pi}

So the Fourier series expansion for f(x) is

f(x)\sim\dfrac{11}4-\dfrac{14}{\pi^2}\displaystyle\sum_{n\ge1}\frac1{(2n-1)^2}\cos\frac{(2n-1)\pi x}7+\frac7\pi\sum_{n\ge1}\frac{(-1)^{n+1}}n\sin\frac{n\pi x}7

What is 240 divided by 6
Reil [10]

Answer:

40

Step-by-step explanation:

Step 1:

Start by setting it up with the divisor 6 on the left side and the dividend 240 on the right side like this:

             

   6 ⟌ 2 4 0

Step 2:

The divisor (6) goes into the first digit of the dividend (2), 0 time(s). Therefore, put 0 on top:

       0    

   6 ⟌ 2 4 0

Step 3:

Multiply the divisor by the result in the previous step (6 x 0 = 0) and write that answer below the dividend.

       0    

   6 ⟌ 2 4 0

      0    

Step 4:

Subtract the result in the previous step from the first digit of the dividend (2 - 0 = 2) and write the answer below.

       0    

   6 ⟌ 2 4 0

     - 0    

       2    

Step 5:

Move down the 2nd digit of the dividend (4) like this:

       0    

   6 ⟌ 2 4 0

     - 0    

       2 4  

Step 6:

The divisor (6) goes into the bottom number (24), 4 time(s). Therefore, put 4 on top:

       0 4  

   6 ⟌ 2 4 0

     - 0    

       2 4  

Step 7:

Multiply the divisor by the result in the previous step (6 x 4 = 24) and write that answer at the bottom:

       0 4  

   6 ⟌ 2 4 0

     - 0    

       2 4  

       2 4  

Step 8:

Subtract the result in the previous step from the number written above it. (24 - 24 = 0) and write the answer at the bottom.

       0 4  

   6 ⟌ 2 4 0

     - 0    

       2 4  

     - 2 4  

         0  

Step 9:

Move down the last digit of the dividend (0) like this:

       0 4  

   6 ⟌ 2 4 0

     - 0    

       2 4  

     - 2 4  

         0 0

Step 10:

The divisor (6) goes into the bottom number (0), 0 time(s). Therefore put 0 on top:

       0 4 0

   6 ⟌ 2 4 0

     - 0    

       2 4  

     - 2 4  

         0 0

Step 11:

Multiply the divisor by the result in the previous step (6 x 0 = 0) and write the answer at the bottom:

       0 4 0

   6 ⟌ 2 4 0

     - 0    

       2 4  

     - 2 4  

         0 0

           0

Step 12:

Subtract the result in the previous step from the number written above it. (0 - 0 = 0) and write the answer at the bottom.

       0 4 0

   6 ⟌ 2 4 0

     - 0    

       2 4  

     - 2 4  

         0 0

     -     0

           0

You are done, because there are no more digits to move down from the dividend.

The answer is the top number and the remainder is the bottom number.

Therefore, the answer to 240 divided by 6 calculated using Long Division is:

40

0 Remainder
