write the expression as a single trigonometric function: tan4θ? +tan 2θ?÷1- tan4θ? tan 2θ? A. tan 6θ? B. cot 6θ? C, tan 4θ? D. cot 4θ? my answer is d can some one tell me if i'm correct
hi amber, can you write down the problem again? I can't understand the denominator. :(
tan 4θ + tan 2θ / 1- tan 4θ tan 2θ A. tan 6θ? B. cot 6θ? C, tan 4θ? D. cot 4θ?
It's A. tan(6θ). It's the tangent case for sum of angles. I took this from wikipedia: http://upload.wikimedia.org/math/5/1/a/51ae1ae6b131eedcf53585e6fe0b72ed.png Hope it helps :)
