Question

Mark any solutions to the equation tan2x - 3 = 0.

A. 2π/3
B. π
C. -π/3
D. 5π/3

Answer 1

oops that's suppose to be tan^2 x - 3 = 0

Answer 2

Answer 3

Hum,　this equation is
\[\tan(2x-3)=0\]
right?

Answer 4

No its \[\tan ^{2}-3=0\]

Answer 5

\[\tan^2x-3=0\]

Answer 6

OK.
\[\tan^{2}x-3=0\]
\[(\tan x+\sqrt{3})(\tan x-\sqrt{3})=0\]
\[\tan x=\pm \sqrt{3}\]
\[x=\pm \frac{ \pi }{ 3 }\]

You select the positive value.
So answer is C.

Answer 7
