|
||||
- Cosine and secant are **even**
|
||||
- Sine, tangent, cosecant, and cotangent are **odd**.
|
||||
## Examples
|
||||
### Even and Odd Functions
|
||||
> If $cot\theta = -\sqrt{3}$, what is $cot(-\theta)$?
|
||||
|
||||
$cot$ is an odd function, and so $cot(-\theta) = \sqrt{3}$
|
||||
### Simplifying Using Identities
|
||||
> Simplify $\frac{sin\theta}{cos\theta}$
