Question

How do you write the trigonometric form into a complex number in standard form `3(cos(18^o 45')+isin(18^o 45')`?

Answer 1

`color(purple)("Complex number is " 2.8408 + 0.9643 i`

Explanation:

Trigonometric form to complex form.

`x = r cos theta = 3 * cos (18^@ 45') = 2.8408`

`y = r sin theta = 3 * sin (18^@ 45') = 0.9643`

`color(purple)("Complex number is " 2.8408 + 0.9643 i`
