Question

If 2tanx/1-tan^2 x = then x can equal:?

there can be more than 1 answer

x= 7pi/8 + npi

x= 5pi/8 + npi

x= 3pi/8 + npi

x= pi/8 + npi

Answer 1

um wat's it equal to?

Answer 2

that's what I'm asking...

Answer 3

it'sin2x i think

Answer 4

there are 4 options I can choose from, they are written under the equation..

Answer 5

like :-/ i think the qn s incomplete

Answer 6

these are the options I can choose from:
x= 7pi/8 + npi

x= 5pi/8 + npi

x= 3pi/8 + npi

x= pi/8 + npi

Answer 7

one(or more) of those options are equal to this equation: 2tanx/1-tan^2 x

Answer 8

it should be last one i guess........ig qn is 2tanx/1-tan^2 x =cos2x

Answer 9

nd if qn is 2tanx/1-tan^2 x =1 upon root 2...answers 3rd nd 4th
2tanx/1-tan^2 x =- 1/root 2 1st nd second
