We can observe that the table of natural sines and natural cosines are generally divided into the following parts. They are the following:. This part of the table is known as Mean Difference Column. Solved examples using the table of natural sines and natural cosines:. Then we move horizontally to the right at the top of the column headed by 0' and read the figure 0. Then we move horizontally to the left at the bottom of the row above the column 0' and read the figure 0. Then we move horizontally to the right at the top of the column headed by 30' and read the figure 0.
In mathematics , the trigonometric functions also called circular functions , angle functions or goniometric functions   are real functions which relate an angle of a right-angled triangle to ratios of two side lengths. They are widely used in all sciences that are related to geometry , such as navigation , solid mechanics , celestial mechanics , geodesy , and many others. They are among the simplest periodic functions , and as such are also widely used for studying periodic phenomena, through Fourier analysis. The most widely used trigonometric functions are the sine , the cosine , and the tangent. Their reciprocals are respectively the cosecant , the secant , and the cotangent , which are less used in modern mathematics. The oldest definitions of trigonometric functions, related to right-angle triangles, define them only for acute angles. For extending these definitions to functions whose domain is the whole projectively extended real line , one can use geometrical definitions using the standard unit circle a circle with radius 1 unit.
