have you seen this formula before?

hsmt Group TitleBest ResponseYou've already chosen the best response.0
now think about the angle a=4theta and the angle b=2theta. does this help?

I'm confused on how I solve it with the this formula using the 'theta'

hsmt Group TitleBest ResponseYou've already chosen the best response.0
ok. well, it is more recognition than solving. look at the form of the equation i gave you and the relation you wrote above. write this puppy as the tangent of the sum of the two angles you have been given (4theta and 2theta)

it is good to ask questions if you are in doubt. :)

Sorry, If it takes to long to respond, I'm still confused a little so I'm trying to write it down so that would hopefully help me get it

no problem. so the form of the equation is tan (a+b)=(tan a +tan b)/(1tan a tan b). substitute for a 4theta and for b 2theta

So, tan 4theta + tan 2theta / 1 tan 4theta * tan 2.?

hsmt Group TitleBest ResponseYou've already chosen the best response.0
we are interested in the left side. the tan (a+b) part. this condenses the mess you were given.

So 4 theta + 2 theta.?

hsmt Group TitleBest ResponseYou've already chosen the best response.0
which becomes tan ?

gjhfdfg Group TitleBest ResponseYou've already chosen the best response.1
You would add the 4 & 2 together & get 6 & 6 would be the tan wouldn't it.?
 2 years ago

hsmt Group TitleBest ResponseYou've already chosen the best response.0
perfect. yes!! so you tan 6theta, which is the trig function (tan) of a single angle 6theta.
