sinusovým

Sinusovým is the instrumental singular form of the Czech adjective sinusový. It is used to describe something related to a sinus in different technical contexts or linguistic usage, depending on the noun it modifies. The root sinus derives from Latin sinus and in Czech is used in mathematics to refer to sine-related concepts and in anatomy to refer to cavities such as the sinuses in the skull.

As an adjective, sinusový is declined like other -ový adjectives; in the instrumental singular masculine it becomes sinusovým. This form is used when the modified noun is in the instrumental case, for example in phrases that convey “with a sinus-related” attribute.

In mathematics and related sciences, sinusový may occur in compounds that indicate relation to sine or sinusoidal shapes, though modern Czech frequently prefers more specific terms such as sinusoidní or funkce sinus for the sine function. In anatomy, sinusový describes features connected to sinuses, with usage depending on the noun being described.
