### Usage

    dcard(theta, mu, r)

### Arguments

`theta` | vector of angles measured in radians at which to evaluate the density function.
`mu` | mean direction of the distribution.
`r` | concentration parameter of the distribution. Absolute value of r must be less than 0.5.

### Value

Returns the cardoid density function evaluated at theta.
