SOLUTION: Write the complex number z = -6 -2i in trigonometric form (sometimes called polar form). Express the angle θ in radians, where 0 <= θ < 2 pi
Z = ___(cos___ + i sin __
Question 1070700: Write the complex number z = -6 -2i in trigonometric form (sometimes called polar form). Express the angle θ in radians, where 0 <= θ < 2 pi
Z = ___(cos___ + i sin ____)
I greatly appreciate an answer to this question.
The answer I am getting is:
r = 6.32456
θ = -161.565 Degrees
But i do not know how to put it in cosine + i sin form.
You can put this solution on YOUR website! Your answer is partially correct.
Your angle should be in radians and not degrees. is the conversion from radians to degrees.
Also,the angle needs to be between (,).
You need to add or .

Also, you can keep the radical form and then there's no need for approximations,

-----------
r = 2sqrt(10) (as you stated)
Theta = atan(-2/-6) =~ 198.43º
Theta = 3.46 radians
=====================
z = 2sqrt(10)cis(theta)
