Precalculus: express the complex number in trigonometric form.

-2. plz really need . no explanation is necessary

  2∠180° . . . or . . . 2(cos(180°) +i·sin(180°))

Step-by-step explanation:

-2 is 2 units along the negative real axis. The direction of that from the origin is at an angle of 180° measured from the positive real axis. So, the magnitude is 2 units and the angle is 180°.

answer: 0,6

step-by-step explanation:

this would make it the y intercept.

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )
