Best ResponseYou've already chosen the best response.0what do you want to do with it?

Best ResponseYou've already chosen the best response.0\[\sqrt 3 \tan (2x) = 0\] first step divide both sides by \(\sqrt{3}\) what do you get?

anonymous

Best ResponseYou've already chosen the best response.0nope. \[\tan (2x) =\frac {0}{\sqrt3}\] now simplify this

Best ResponseYou've already chosen the best response.0oh dear! sorry i didnt realise! The question is sqrt(3) tan2x+1=0

anonymous

Best ResponseYou've already chosen the best response.0haha..then you're right \[\tan(2x) =\frac{1}{\sqrt 3}\]

Best ResponseYou've already chosen the best response.0now second step. take the arctangent of both sides

Best ResponseYou've already chosen the best response.0oh ok so when you say take the arctangent, where do you go from there?

anonymous

Best ResponseYou've already chosen the best response.0so \[2x = \frac{\pi}{6}\] now you divide both sides by 2

anonymous

Best ResponseYou've already chosen the best response.0is this one of the answers?

anonymous

Best ResponseYou've already chosen the best response.0well there are 4 values for x right?

anonymous

Best ResponseYou've already chosen the best response.0because there was a 2 between the tan and the x, which compresses the tan graph

anonymous

Best ResponseYou've already chosen the best response.0i cant remember that part...is it adding \(\pi\) or \(2\pi\)

anonymous

Best ResponseYou've already chosen the best response.0what do you mean 2 between tan and x..tan (2x)?

anonymous

Best ResponseYou've already chosen the best response.0yeah, thats what i meant tan2x

Best ResponseYou've already chosen the best response.0just add pi to the solution and it wont matter.

anonymous

Best ResponseYou've already chosen the best response.0yep i do think its another answer.

Best ResponseYou've already chosen the best response.0however, in the back of my text book the answers are 5pi/12 11pi/12 17pi/12 and 23pi/12

anonymous

Best ResponseYou've already chosen the best response.0and im wondering how my magic maths textbook got there

anonymous

Best ResponseYou've already chosen the best response.0so we are going good with the 11pi/12 :D

anonymous

Best ResponseYou've already chosen the best response.0and if pi is added again, we get 23pi/12 which is also good!

anonymous

Best ResponseYou've already chosen the best response.0you're doing right. so is there a further problem?

anonymous

Best ResponseYou've already chosen the best response.0well there are sposed to be 4 answers

anonymous

Best ResponseYou've already chosen the best response.0then you add pi again

anonymous

Best ResponseYou've already chosen the best response.0subtract a pi, if want int he interval, [2pi,2pi]

anonymous

Best ResponseYou've already chosen the best response.0well i have 11pi/12 and 23pi/12

anonymous

Best ResponseYou've already chosen the best response.011pi/12  pi is pi/12 (bringing you back to the orig thingy)

Best ResponseYou've already chosen the best response.0thats not one of the answers :?

Best ResponseYou've already chosen the best response.0You started with 2x= pi/6 if we call 2x theta, we have 2 solutions: dw:1342706814544:dw and x is 5pi/12 and 11pi/12 now add pi to each value to get the other 2 solutions or , noting that 2x+pi divided by 2 is x+pi/2 , add multiplies of pi/2 to get all four solutions starting with pi/12 (which is 11pi/12 in the interval [0, 2pi] )
