### Trigonometry Problems

By using different trigonometry concepts, we can measure the width of a river or the height of any building. To do so, you need to have your basics right. For instance, 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.

• $\alpha$ (Alpha)
• $\beta$ (Beta)
• $\theta$ (Theta)
• $\gamma$ (Gamma)
• $\phi$ (Phi)
• $\lambda$ (Lamda)

and so on to indicate the measure of an angle.

Let us call $\angle$ as $\theta$ (Theta).

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 $\theta$: It is defined as the ratio of the side opposite to q and the hypotenuse.

i.e., $\sin \theta = \frac{Opposite side}{Hypotenuse}$=$\frac{BC}{AC}$

In short we write $\sin \theta \frac{BC}{AC}$

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

$Cosine \theta =\frac{Adjacent side}{Hypotenuse}=\frac{BC}{AC}$

In short,

(III) Tangent $\theta$: It is defined as the ratio of the side opposite to q and the adjacent side,

$Tangent \theta =\frac{Opposite side}{Adjacent side}=\frac{BC}{AB}$

In short, $\tan \theta=\frac{BC}{AB}$

Similarly three more ratios can be obtained by taking the reciprocals of $\sin\theta,\cos\theta$ and $\tan\theta$.

(IV) Cosecant $\theta$ is the reciprocal of $\sin\theta$

It is written as cosec $\theta$,

$cosec\theta=\frac{1}{\sin\theta}$

(V) Secant $\theta$ is the reciprocal of cos $\theta$.

It is written as sec $\theta$,

$sec\theta=\frac{1}{\cos\theta}$

(VI) Cotangent $\theta$ is the reciprocal of tan $\theta$.

It is written as cot $\theta$,

$cot\theta=\frac{1}{\tan\theta}$
