...APM = = -5 = cosec A . These results may also be expressed thus : the sine of an angle is the cosine of the complement of that angle ; the tangent of an angle is the co-tangent of the complement of that angle; the secant of an angle is the cosecant of the complement of that angle....

...A. KULES AND PRINCIPLES OF MATHEMATICS. Hence it may be seen that the sine of an angle is the cosine of the complement of that angle; the tangent of an ang'le is the cotangent of its complement, A and the secant of an angle is the cosecant of it« complement. The functions of angles...

...cosecant, and coversed sine appears from the above. The cosine of an angle is the complement-sine, ie the sine of the complement of that angle: the tangent...left number of the equation, we proceed as follows: „„ 4 sin A cot A = sin A ^Jl (Art. 16, (2).) sin A = cos A. .-. sin A cot A =cos.4. 2. cos A tan...
