Direction cosines and direction ratios are used to describe the orientation of a line or a vector in three-dimensional space. Direction cosines are the cosines of the angles that a given line or vector makes with the positive x, y, and z axes of a Cartesian coordinate system. For example, if the angles that a…
Trigonometric functions are mathematical functions that relate the angles of a right triangle to the lengths of its sides. The most commonly used trigonometric functions are sine (sin), cosine (cos), and tangent (tan). These functions can be defined in terms of the sides of a right triangle as follows: In addition to these three functions,…
Trigonometry is a branch of mathematics that deals with the relationships between the angles and sides of triangles. It is a fundamental tool in many areas of science and engineering, including physics, astronomy, and navigation. The three primary trigonometric functions are sine, cosine, and tangent. These functions are defined based on the ratios of the…
