The product of the cosine function and the cosine of sine function and the cosine of sine of sine function and the cosine of sine of sine of sine function is the product of four functions: the cosine function, the cosine of sine function, the cosine of sine of sine function, and the cosine of sine of sine of sine function.

This function is also the derivative of the sine of sine of sine of sine function.

## Notation Edit

It is notated as $x \mapsto \cos \left( x \right) \cos \left( \sin \left( x \right) \right) \cos \left( \sin \left( \sin \left( x \right) \right) \right) \cos \left( \sin \left( \sin \left( \sin \left( x \right) \right) \right) \right)$
