script to display trigonometric table. just a simple one which echo given data , that's all.
Trigonometry (from Greek trigonon "triangle" + metron "measure") is a branch of mathematics that studies triangles and the relationships between their sides and the angles between these sides. Trigonometry defines the trigonometric functions, which describe those relationships and have applicability to cyclical phenomena, such as waves. The field evolved during the third century BC as a branch of geometry used extensively for astronomical studies. It is also the foundation of the practical art of surveying.

HOW THIS SCRIPT WORKS:
Absolutely nothing to explain here!
Just 'echo'ing with necessary colour changes.

Don't know what to do with codes ?? click here

ReplyDeleteIt’s concise and practical showing a clean way to output a trigonometry table using Bash is both clever and instructive. I especially appreciated how the code aligns with the theory of triangles and trigonometric functions. For anyone teaching or learning with math tuition, this kind of hands-on script adds a fun computational layer to theoretical concepts.
