Question

Which of the following is a solution to tanx+3 √ =0 ?

Answer 1

Sorry, I can't see it very clearly. Is it \(tan x +\sqrt3 = 0\)?

Answer 2

yes it is

Answer 3

So \(tanx = -\sqrt3\), right? Now we can use the inverse function.

Answer 4

yes correct

Answer 5

So \(x=tan^{-1}(-\sqrt3)\). Can you find x?

Answer 6

is it 150

Answer 7

I think it is 120

Answer 8

120 is not an option 150, 60, 240, or 300

Answer 9

Tangent function repeats every 180, so you can easily calculate the next value.

Answer 10

120+180

Answer 11

300

Answer 12

Yes. You can also look at the unit circle. \(tan(300) =-\sqrt3\) too

Answer 13

i dont have a unit circle with me but you are correct thank you so much

Answer 14

You are welcome.
