Question

Consider the equation 3tan^2(x)-1=0.

Answer 1

solve for x ?
find exact solutions ??

Answer 2

60degrees

Answer 3

oh yea
alright solve for tan

Answer 4

Im still trying to figure it out really.

Answer 5

ah i see 2pi/3 5pi/3 is ur answer ??

Answer 6

\[3\tan ^{2}x=1\]

Answer 7

\[\tan ^{2}x=1/3\]

Answer 8

No its just hat i had accidentally clicked

Answer 9

what's the rush ?

Answer 10

Like I need it in the form that is on the questions, I really almost have no Idea what im doing here.

Answer 11

alright first we have to solve for tanx
someone already solved first 2 steps

Answer 12

\[\huge\rm 3\tan^2(x)-1=0\]
to solve for tan
first add one both sides
we need tan itself at left side
so divide both sides by 3
\[\tan^2(x) =\frac{1}{3}\]

Answer 13

what would be the next step ?
how would you cancel out the square from tan^2 ?

Answer 14

Would you separate it where it is:

(tan)(tan) and cancel one making it just Tan?

Like I said I'm kind of lost, so I'm not entirely sure.

Answer 15

let tan(x) =y \[\huge\rm y^2=\frac{1}{3}\]
do you know wha would you do to cancel out the square ??? :=))

Answer 16

let me know if u r not sure :=))

Answer 17

I am not entirely sure, I am way better at english. . . I hate math.

Answer 18

hm alright
to cancel out the square we should take `square root`
square and square cancelz each other out \[\sqrt{x^2} = x\]

Answer 19

so take square root `both sides ` of the equal sign

Answer 20

ok, so it would be \[√x^2=x^2\]?

Answer 21

Wait

Answer 22

\[√x^2=√x\]

Answer 23

hmm no square and square cancels each other ot this is an example btw
