Trigonometry
is based on the study of right-angled triangles. This is a form of geometry that developed out of the study of the stars. It is also concerned with the relationships that exist between the sides and angles of triangles, and their measurement. comes in two forms, spherical and plane. Spherical is the study of curved triangles lying on the surface of a hypothetical sphere, which is mainly used by astronomers and navigators. Plane is the study of more variety and is mainly focused on by many books on . In , the ratio between any two sides of a right-angled triangle is given as a function of angles within the triangle. These ratios are called trigonometric functions. Even though ...

the side adjacent to 0, to h, the length of the hypotenuse. The tangent is the ratio of o, the length of the side opposite 0, to a, the length of the side adjacent to 0.
sin 0 = o/h
cos 0 = a/h
tan 0 = o/a
is considered to be an important component within every mathematics course, while its rules and formulae, the plural form of formula, has applications in subjects ranging from engineering to navigation. An example of it being used for engineering is the Egyptians using it for building their pyramids. The functions of an acute angle that deal with any right triangle, it will be convenient to denote the vertices, the point at which the sides of an angle intersect, as A, B, and C with C the vertex of the right angle, to denote the angles of the triangles as A, B, and C = 90 , and to denote the sides opposite the angles as a, b, and c. With respect to angle A, a will be called the opposite side and b will be called the adjacent side; with respect to angle B, b will be called the ...
