WebTrigonometry. Trigonometry (from Ancient Greek τρίγωνον (trígōnon) 'triangle', and μέτρον (métron) 'measure') is a branch of mathematics concerned with relationships between angles and ratios of lengths. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies. WebCorrect option is A) By, Fundamental Properties of f(x) periodic function with Period T. f(x+T)=f(x) Let f(x)=cos 6x+sin 6x. assume from option smallest period of f(x)=π/2 ∴f(x+π/2)=f(x) ∴sin 6(x+π/2)+cos 6(x+π/2)=cos 6x+sin 6x. This shows that 2π is a fundamental period of f(x). Was this answer helpful? 0 0 Similar questions
