kalkulusi

Kalkulusi is a Turkish term that grammatically denotes the possessive form of kalkulus (calculus), literally meaning “his calculus” or “its calculus.” Turkish forms possession by attaching suffixes to the noun; for kalkulus the third-person possessive suffix yields kalkulusu, and in some spellings or texts the form kalkulusi may also be encountered. The base noun kalkulus is used in Turkish mathematics to refer to the subject of calculus.

Calculus is the branch of mathematics that studies change and motion, using limits, derivatives, and integrals. It has two main branches: differential calculus, which concerns rates of change and slopes of curves, and integral calculus, which concerns accumulation and areas. More advanced topics include multivariable calculus, vector calculus, and differential equations. Together, these tools model phenomena in physics, engineering, economics, biology, computer science, and beyond.

Historically, calculus was developed independently in the 17th century by Isaac Newton and Gottfried Wilhelm Leibniz. Its foundations were strengthened in the 18th and 19th centuries through the rigorous notions of limits and continuity advanced by Cauchy and Weierstrass, with later expansions in analysis, topology, and measure theory. The subject has since become a core component of mathematics education worldwide and a foundational tool across the sciences.

In Turkish education, kalkulus is taught at secondary and tertiary levels, introducing limits, derivatives, integrals, infinite series, and their applications. The term kalkulusi would typically appear in sentences indicating possession, such as “kalkulusunu çözdü” (he solved his calculus), among other constructions.
