Question

what is the standard form of 2cis210 degree?​

Answer 1

Answer:

$2( \cos(210°) + \sin(210°) )$

Answer 2

Answer:

The correct answer of this question is $2(cos(210$ °$)$ $+sin(210$°$)$$)$

Step-by-step explanation:

Given - The standard form of $2cis210$ degree.

To Find - what is the standard form of $2cis210$ degree?

$cis x$ $= cos x + I sin x$ is a mathematical notation where $cos$ is the cosine function, $I$ is the imaginary unit, and $sin$ is the sine function.

The standard form of $2cis210$ degree is

$2(cos(210$ °$) + sin(210$ °$)$
