The word "Trigonometrical" is spelled with 5 syllables: /ˌtrɪɡəˈnɒmɪtrɪkəl/. The first syllable is stressed and pronounced as "tri-" (/traɪ/), followed by "go-" (/ɡəʊ/) and "-no-" (/nəʊ/). The fourth syllable is pronounced as "-metr-" (/me.trə/), followed by "-i-" (/ɪ/) and the final syllable "-cal" (/kəl/). This word refers to the branch of mathematics dealing with the relationships between the sides and angles of triangles, and is often used in various scientific fields.
Trigonometrical is an adjective that relates to or pertains to trigonometry, which is a branch of mathematics that focuses on the relationships between the angles and sides of triangles. Trigonometry is primarily concerned with the study of trigonometric functions, such as sine, cosine, and tangent, which describe these relationships.
When referring to something as "trigonometrical," it implies that it is related to or involves the principles, concepts, methods, or calculations of trigonometry. This term can be used to describe various aspects, such as trigonometrical equations, trigonometrical identities, trigonometrical measurements, or trigonometrical calculations.
Trigonometrical equations are mathematical expressions that involve trigonometric functions and aim to solve for unknown angles or sides in a triangle. Trigonometrical identities refer to mathematical equalities involving trigonometric functions that can be used to simplify or manipulate trigonometric expressions. Trigonometrical measurements involve using trigonometry to measure angles or distances in real-world applications, such as surveying or engineering. Trigonometrical calculations encompass the computations and mathematical operations performed using trigonometric principles.
In summary, the term "trigonometrical" refers to anything that is related to or associated with trigonometry—its concepts, functions, principles, calculations, identities, or applications.
Performed by or according to the rules of trigonometry.

The word "trigonometrical" has its origins in Latin and Greek. The term is derived from the Latin word "trigonum", which means "triangle", and the Greek word "metron", which means "measure".
In Ancient Greece, trigonometry was primarily concerned with the measurement of triangles, hence the inclusion of "trigonum" in the etymology. The Greeks used trigonometry to measure and calculate various aspects of triangles, such as angles, sides, and the relationships between them.
Over time, the field of trigonometry expanded beyond triangle measurements and started encompassing the study of angles and their relationships in general. Therefore, the term "trigonometrical" came to be used to describe anything relating to the measurement and calculation of angles and their trigonometric functions.
