Question

Express the complex number in trigonometric form.

3

Answer 1

the answers that i have are:

3(cos 0° + i sin 0°)

3(cos 90° + i sin 90°)

3(cos 180° + i sin 180°)

3(cos 270° + i sin 270°)

Answer 2

you should be aware of the values for those trig functions ...

which one simplifies to your answer?

Answer 3

the first one?

Answer 4

@amistre64

Answer 5

3(cos0 + isin0)

3(1 + i0) = 3, yes

Answer 6

okay

Answer 7

Can you help me with another?

Answer 8

maybe, depends on what it is :)

Answer 9

Express the complex number in trigonometric form.

3 - 3i

Answer 10

what would you suggest we try first?

Answer 11

i have no idea

Answer 12

my idea is to first factor out the 3, what does that do for us?

Answer 13

3(1-i)

Answer 14

website is not acting nicely is it

Answer 15

you are correct, now, we know that the trig parts resembles

cos(x)+i sin(x)

so equate cos(x) to 1
nd sin(x) to -1

Answer 16

hmmm, that seems a little off to me now that i glance at it
