Question

How do you add `(8-3i)+(7+4i)` in trigonometric form?

Answer 1

`(sqrt226, tan(1/15))`

Explanation:

If you add them together you get:

`15 + i`

I'm not sure what you mean "trigonometric form" but to convert to polar form `(r, theta)` you have

Standard complex form: `ax +bi`

`r = sqrt(a^2+b^2)`

`r = sqrt(15^2+1^2)`

`r = sqrt(15^2+1^2)`

`r=sqrt226`

`theta = tan(b/a)`

`theta = tan(1/15)`
