Best ResponseYou've already chosen the best response.1I'm confused on how I solve it with the this formula using the 'theta'

Best ResponseYou've already chosen the best response.0ok. 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)

Best ResponseYou've already chosen the best response.1Sorry, 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

Best ResponseYou've already chosen the best response.0no 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

Best ResponseYou've already chosen the best response.1So, tan 4theta + tan 2theta / 1 tan 4theta * tan 2.?

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

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

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