sekansimeve

Sekansimeve is a term that appears in historical contexts, particularly related to the early development of mathematics and astronomy in the Islamic world. It is generally understood to refer to tables or calculations involving secant functions. The secant function, in trigonometry, is defined as the reciprocal of the cosine function, or 1/cos(x).

The development of trigonometry in Islamic scholarship was significant, building upon earlier Greek and Indian mathematical traditions. Scholars of the medieval Islamic period made substantial contributions to the field, including the introduction and systematization of trigonometric functions like sine, cosine, tangent, cotangent, secant, and cosecant. These advancements were crucial for various applications, including astronomy, navigation, surveying, and timekeeping.

The existence of "sekansimeve" would imply the existence of methods or instruments for calculating or tabulating values of the secant function. While specific surviving detailed tables explicitly named "sekansimeve" might be rare or difficult to identify without specialized historical research, the understanding and use of the secant function itself are well-documented in mathematical texts from that era. Islamic astronomers and mathematicians were known for their precise calculations and the creation of extensive astronomical tables, which often included trigonometric values necessary for their work. The term itself likely reflects the Arabic or Persian nomenclature used at the time for these mathematical tools.
