Question

Use even odd properties tan(-11π/6)

Answer 1

Hmm I'm not sure what they mean by even odd properties.
I guess you could consider the fact that tangent is an `odd` function.
Meaning that, \[\large \tan\left(-\frac{11\pi}{6}\right) \qquad = \qquad -\tan\left(\frac{11\pi}{6}\right)\]

Answer 2

If you don't remember your tangent special angles, you can always rewrite it in terms of sines and cosines,\[\large -\tan\left(\frac{11\pi}{6}\right) \qquad = \qquad -\frac{\sin\left(\dfrac{11\pi}{6}\right)}{\cos\left(\dfrac{11\pi}{6}\right)}\]

Answer 3

Ok so what would the answer be?
