The trigonometric form of the complex number given in the task content is; 18(isin(π/2)).

<h3>What is the trigonometric form of the complex number?</h3>

If follows from the task content that the complex number whose trigonometric representation is to be determined is; 18i.

Hence, It follows that the trigonometric form is;

= 18(cos(π/2) + isin(π/2)). where; cos(π/2) = 0.

Hence, we have;

= 18(isin(π/2)).

Solve for y, then find the value of y for each value of x.
Misha Larkins [42]

Answer:

4,8,6

Step-by-step explanation:

replace x with 0

2y+4(0)=8

multiply 4 and 0

2y+0=8

2y=8

divide each term by 2

\frac{2y}{2} =\frac{8}{2\\}

simplify

y=4

repeat with -2 and -1

2y+4(-2)=8

2y-8=8

2y=8+8

2y=16

\frac{2y}{2}=\frac{16}{2}

y=8

2y+4(-1)=8

2y-4=8

2y=8+4

2y=12

\frac{2y}{2} = \frac{12}{2}

y=6

Write your question here (Keep it simple and clear to get the best answer)4x³-5x is it odd or even function
Dvinal [7]

Answer:

odd

Step-by-step explanation:

To determine if odd/ even

• If f(x) = f(- x) then it is even

• If f(- x) = - f(x) then it is odd

Given

f(x) = 4x³ - 5x , then

f(- x) = 4(- x)³ - 5(- x) = - 4x³ + 5x

Since f(x) ≠ f(- x) then it is not even

- f(x) = - (4x³ - 5x) = - 4x³ + 5x

Since f(- x) = - f(x) , then 4x³ - 5x is odd
