A. x=pi/6+npi
B. x=pi/3+npi
C. x=2pi/3+npi
D. x=5pi/6+npi

Answer 1

tan(2x)=sqrt3 -> 2x=pi/3 -> pi/6+npi

Answer 2

how did you get that answer

Answer 3

it's just a trigonometric identity to play with :)

Answer 4

which one?

Answer 5

so its D

Answer 6

right?

Answer 7

the left one

Answer 8

tan(2x)=\[\sqrt{3}\]

Answer 9

yeah, you only have to mind the sings

Answer 10

and by the way it's D :)

Answer 11
