We prove here that the tangent function tan (-x) = - tan x is odd using the unit circle.
• unit circle $\mathcal{C}(O,R=1)$
• definition of the angle $x$
• definition of the angle $-x$
Now consider the triangles: $(OA_xA)$ and $(OA’_xA’)$.
## Proof that tangent is an odd function tan(-x) = -tan (x)

The answer is x in ] -2,+2 [ uu ] 6, +oo[
#### Explanation:
Let $f \left(x\right) = {x}^{3} - 6 {x}^{2} - 4 x + 24$
As a polynomial, the domain of $f \left(x\right)$ is ${D}_{f} \left(x\right) = \mathbb{R}$
Then, by trial and error,
