Question

How do you write the trigonometric form into a complex number in standard form `10(cos((2pi)/5)+isin((2pi)/5))`?

Answer 1

`(3.090169938 + 9.510565165 i)`

Explanation:

`10(cos((2pi)/5)+ i sin((2pi)/5))`

`10cos((2pi)/5)=3.090169938`

`10(i sin((2pi)/5))=9.510565165 i`

`(3.090169938 + 9.510565165 i)`
