Answer:

8.6615988

Step-by-step explanation:

f(x) = 3 sin (x) / ( 1 + cos x)

To find the derivative bottom * d/ dx top - top d/dx bottom all over the bottom squared

d/dx = 3 ( ( 1 + cos x) cos x - sin x( - sin x)) / ( 1 + cos x) ^2

= 3 ( cos x + cos ^2 x + sin ^2 x) / ( 1 + cos x) ^2

= 3 ( 1 + cos x) / ( 1 + cos x) ^2

= 3 / ( 1 + cos x)

Let x = 4

3 / ( 1 + cos 4)

Assuming x is in radians

3/.346356

Type an equation for the following pattern

umka2103 [35]

For the given table, the difference between two consecutive y terms are

$4-3=5-4=6-5=7-6=1$

It means the difference is constant. So the given function is in arithmetic progression.

And to find the equation, representing the given series, we will use the formula for the nth term of arithmetic series, which is

$a_{n}= a+ (n-1)d$

Here,

$a_{n} =y, n=x, and \ d \ for \ the \ common \ difference.$

So we will get

$y= 3+(x-1)(1)
\\
y = 3 + x-1
\\
y= x +2$

Solve the following equation. Then place the correct number in the box provided. x/6=3

Aliun [14]

Answer:

x=18

Step-by-step explanation:

if x/6=3, the you can use the mulitplication property of equations to solve. so multiply each side by 6. it will eliminate the fraction on the left side of the equal side, leaving you with x and then 6x3=18, therefore

x=18

2/5 - 1/3 (simplified if possible)

Kipish [7]

Answer:

1/15

Step-by-step explanation:

(1). Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD (Least Common Denominator).

So lets do step one now, the LCD is 15 so we have to make both denominators agree on one number, so 15 is the number both denominators agree on.

Solve:

2*3/5*3 - 1*5/3*5

(2). Complete the multiplication.

6/15 - 5/15

(3). The two fractions now have like denominators so you can subtract the numerators.

6 - 5 / 15 - 15 = 1/15

*Pro tip:

The denominator doesn't change and stays the same. So you don't 

subtract the 15 by 15.

(4). Then you'll get the answer and then if you can simplify then simplify.

The Answer is 1/15, and cannot be simplified.

So the answer is 1/15

Hope this helps!
