Question

finally, give the root in polar form.
r = 2 θ = 228°
?(cos □° + i sin □°)

Explanation:

Step1: Recall Polar Form Formula

The polar form of a complex number is \( z = r(\cos\theta + i\sin\theta) \), where \( r \) is the modulus and \( \theta \) is the argument.

Step2: Substitute Given Values

We are given \( r = 2 \) and \( \theta = 228^\circ \). Substituting these into the polar form formula, we get \( z = 2(\cos 228^\circ + i\sin 228^\circ) \).

Answer:

\( 2(\cos 228^\circ + i\sin 228^\circ) \)
