Question

How do you write the trigonometric form into a complex number in standard form `8(cos((pi)/2)+isin((pi)/2))`?

Answer 1

`8(cos((pi)/2)+isin((pi)/2))` in standard form is `0+8i`.

Explanation:

`8(cos((pi)/2)+isin((pi)/2))`

= `8cos((pi)/2)+8isin((pi)/2)`

= `8xx0+8ixx1`

= `0+8i`

which is the complex number in standard form.
