Functions of circular trigonometry

The trigonometric functions of angles are the ratios between the various sides of the reference triangles shown in Fig. 3-38 for the various quadrants. Clearly r = Vx2 + y2 0. The fundamental functions (see Figs. 3-39, 3-40, 3-41) are Plane Trigonometry [Pg.16]

If it is desired to find the angle when a function of it is given, the procedure is as follows There will in general be two angles between 0° and 360° corresponding to the given value of the function. [Pg.16]

Given (a 0) Find an acute angle 0O such that Required angles are [Pg.16]

Other Relations In this subsection, where appropriate, two more formulas can be generated by replacing a by b, b by c, c by a, [Pg.17]

The magnitude and sign of trigonometric functions are presented in Table 1.3. [Pg.22]
