## Spectrum Group Title Which of the following are solutions to (2tanx)/(1- tan^2x) = sqrt(3) more than one avaliable a. x = (pi/3) + nPI b. x = (2pi/3) + nPI c x = (5pi/6) + npi d. x = (pi/6) + nPI one year ago one year ago

d ption correct

2. jishan Group Title

because tanx =tany then x=pi n+y

3. Spectrum Group Title

and?

4. Avva Group Title

you can notice that we are given the double angle formula for tan 2x so we can say that $\tan 2x = \sqrt{3}$ we know that tan is only positive in the first and third quadrant on solving this $\tan^{-1} \sqrt{3} = \frac{ \Pi }{ 3 }$ then the solution will be $\frac{ \Pi }{ 6 }$and its nPi multiplies so it will be d.

5. jishan Group Title

right dear.......

6. Spectrum Group Title

so is it just d ?

7. Avva Group Title

yes doesn't it stated values of n ?

8. Spectrum Group Title

what?

9. Avva Group Title

n pi what are the values of n ?

10. Spectrum Group Title

i don't know?

11. Avva Group Title

well it should be positive integers multiplies of 30 (pi/6)

12. Spectrum Group Title

5pi/6 work?
