Respuesta :

remember to use trig form the general equation is: r(cos(angle) + i sin(angle))
to find r, take √a^2 + b^2 to get 3 for the angle it would be undefined so thee argument would be π / 2. So your answer is 3(cos(π/2) + i sin(π/2))

The complex number in trignometric form. -3i is. 3(cos(π/2) + i sin(π/2) )

How do you find the trigonometric form of a number?

The trigonometric form of a complex number z = a + bi is. z = r(cos θ + i sin θ), where r = |a + bi| is the modulus of z, and tan θ = b. a.

Is trigonometric form the same as a polar form?

Trigonometric or Polar Form of a Complex Number (r cis θ)

Here we will use that basic conversion to rewrite z = a + bi in another (sometimes more convenient) form that is based on the polar conversion. This new form is called the trigonometric form of a complex number.
