With trigonometry we can find the height of a building or the width of a river without actually climbing or crossing. Certain basic definitions are necessary to further develop this subject. The ratios of two sides of a triangle are taken. There are six possible combinations. Each ratio is given a special name.

In this subject we usually use the Greek letters.

(i) (Alpha) (ii) b (Beta) (iii) q (Theta)

(iv) g (Gamma) (v) f (Phi) (vi) l (Lamda)

and so on to indicate the measure of an angle.

Let us call as q.

The side opposite to q is the side BC.

The side adjacent to q is the side AB.

The hypotenuse of the DABC is the side AC.

Now, let us write down the trigonometrical ratios with the help of the above triangles:

(i) Sine q: It is defined as the ratio of the side opposite to q and the hypotenuse.

i.e.,

In short we write sin

(ii) Cosine q: It is defined as the ratio of an adjacent side to q and the hypotenuse,

In short,

(iii) Tangent q : It is defined as the ratio of the side opposite to q and the adjacent side,

In short,

Similarly three more ratios can be obtained by taking the reciprocals of .

(iv) Cosecant q is the reciprocal of sin

It is written as cosec q,

(v) Secant q is the reciprocal of cos q.

It is written as sec q,

(vi) Cotangent q is the reciprocal of tan q.

It is written as cot q,

(i) Sin q means a particular ratio. It is not sin multiplied by q.

(ii) For trigonometrical ratios, short form T-ratios will be used.

(iii) In right angled triangles T-ratios are obtained only for acute angles.

(iv) T-ratios depend on only the magnitude of the angles and not on the size of the triangle.
