3. What is the Definition of Trigonometric Functions?
Ans: Cosine, sine, and tangent are the primary trigonometric functions. The various angles at which we get value for the functions are 00, 300, 600, 900, 1800, 3600. In various trigonometric calculations, 1 cos squared theta, is used. Using six trigonometric ratios that are used in trigonometry, we can perform trigonometric calculations. With these trigonometric ratios, we can solve or derive almost any trigonometric calculations. Sine, cosine, tangent, co-tangent, cos, and cosec are some of the trigonometric functions. Here sine and cosine are the fundamental ratios. Tan, cot, sec is the derived function. Some ratios of sine, cot, and tan are present.
Sinx = opposite/hypotenuse.
Cosx = adjacent/hypotenuse.
Tanx = sin x/cos x.
