TRIGONOMETRY

            The word ‘Trigonometry’ is derived from the Greek words:

        ⇒                                                            Tri                         three

        ⇒
                                                            gon                        sides

         ⇒                                                            metry                    measure

                        “Trigonometry is the study of relationship between the sides and the angles of a triangle”

Trigonometric Ratios

Ratios of the sides of a right triangle with respect to its acute angles, called the trigonometric ratios of the angle.

Reciprocal Relations:
$\begin{array}{l}\left(\text{i}\right)\sin A=\frac{1}{\cos ecA}\\ \left(\text{ii}\right)\cos A=\frac{1}{\sec A}\\ \left(\text{iii}\right)\tan A=\frac{1}{\cot \text{}A}\\ \text{from the above results, it follows that}\\ \sin A.\cos ecA=1\\ \cos A.\sec A=1\\ \tan A.\cot A=1\\ \end{array}$

Quotient Relations: $\begin{array}{l}\left(\text{i}\right)\tan A=\frac{\sin A}{\cos A}\\ \left(\text{ii}\right)\cot A=\frac{\cos A}{\sin A}\end{array}$
