We can immediately write:

2.50e3.84j = 2.50 ∠ 3.84
[polar form, θ in radians]

OR, if you prefer, since 3.84 radians = 220°,

2.50e3.84j = 2.50(cos220° + jsin220°)
[polar form, θ in degrees]

And, using this result, we can write:

2.50e3.84j = 2.50(cos220° + jsin220°) = -1.92 -1.61j
[exponential
form]
[polar form] [rectangular form]
