Best ResponseYou've already chosen the best response.3what do you want to do with it?

lgbasallote

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

amsterdam11

Best ResponseYou've already chosen the best response.1so tan2x=1/sqrt(3)

lgbasallote

Best ResponseYou've already chosen the best response.3nope. \[\tan (2x) =\frac {0}{\sqrt3}\] now simplify this

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

lgbasallote

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

Best ResponseYou've already chosen the best response.3now second step. take the arctangent of both sides

Best ResponseYou've already chosen the best response.1oh ok so when you say take the arctangent, where do you go from there?

lgbasallote

Best ResponseYou've already chosen the best response.3so \[2x = \frac{\pi}{6}\] now you divide both sides by 2

Best ResponseYou've already chosen the best response.1is this one of the answers?

Best ResponseYou've already chosen the best response.1well there are 4 values for x right?

amsterdam11

Best ResponseYou've already chosen the best response.1because there was a 2 between the tan and the x, which compresses the tan graph

Best ResponseYou've already chosen the best response.3i cant remember that part...is it adding \(\pi\) or \(2\pi\)

lgbasallote

Best ResponseYou've already chosen the best response.3what do you mean 2 between tan and x..tan (2x)?

amsterdam11

Best ResponseYou've already chosen the best response.1yeah, thats what i meant tan2x

Best ResponseYou've already chosen the best response.1however, in the back of my text book the answers are 5pi/12 11pi/12 17pi/12 and 23pi/12

Best ResponseYou've already chosen the best response.1and im wondering how my magic maths textbook got there

amsterdam11

Best ResponseYou've already chosen the best response.1so we are going good with the 11pi/12 :D

amsterdam11
 2 years ago
Best ResponseYou've already chosen the best response.1and if pi is added again, we get 23pi/12 which is also good!

lgbasallote

Best ResponseYou've already chosen the best response.3you're doing right. so is there a further problem?

amsterdam11
 2 years ago
Best ResponseYou've already chosen the best response.1well there are sposed to be 4 answers

lgbasallote

Best ResponseYou've already chosen the best response.3then you add pi again

vamgadu

Best ResponseYou've already chosen the best response.1subtract a pi, if want int he interval, [2pi,2pi]

amsterdam11

Best ResponseYou've already chosen the best response.1well i have 11pi/12 and 23pi/12

lgbasallote

Best ResponseYou've already chosen the best response.311pi/12  pi is pi/12 (bringing you back to the orig thingy)

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] )
