# Online Trigonometry Help and Tutoring

Trigonometry is the part of mathematics based on the ratios of the length of the sides of a right angled triangle. There are six basic trigonometric functions - sine, cosine, tangent, cotangent, secant and cosecant. The application of trigonometry varies from aerospace engineering to astronomy to oceanography and many more. To have a good concept of this subject, one has to start from understanding the basics instead of mugging up the formulae.

## Trigonometry Problems

With trigonometry we can find the height of a building or the width of a river without actually  climbing or crossing it. Certain basic definitions and formulas are to be remembered for the best of understanding and to have a right approach towards the subject. Mathematics is not just about learning formulas it’s a way of thinking and solving many problems to develop your skills. We considered six possible combinations between the ratios of two sides of a triangle to solve various problems which are sine, cosine and tangent. These three functions are simply ratios of the sides of triangles that help us relate to an angle in the triangle.

In this subject we usually use the Greek letters.

i) $\alpha$ (Alpha)

ii) $\beta$ (Beta)

iii)
$\theta$ (Theta)

iv)
$\gamma$ (Gamma)

v) $\phi$ (Phi)

vi) $\lambda$ (Lambda)

and so on to indicate the measure of an angle.

Let us call $\angle$ A as $\theta$.

The side opposite to $\theta$ is BC.

The side adjacent to $\theta$ is AB.

The hypotenuse of the $\triangle$ABC is AC.

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

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

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

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

2) $Cosine \ \theta$ : It is defined as the ratio of an adjacent side to $\theta$ and the hypotenuse.

i.e. $Cosine \ \theta$ = $\frac{Adjacent \ side}{Hypotenuse}$ = $\frac{AB}{AC}$

In short,  $cos \ \theta$ = $\frac{AB}{AC}$

3) $Tangent \ \theta$: It is defined as the ratio of the side opposite to $\theta$ 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 $tan \ \theta$.

4)
$Cosec \ \theta$ is the reciprocal of $sin \ \theta$.

It is written as $Cosec \ \theta$,

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

5) $Sec \ \theta$ is the reciprocal of $cos \ \theta$.

It is written as $sec \ \theta$,

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

6)
$Cot \ \theta$ is the reciprocal of $tan \ \theta$.

It is written as $cot \ \theta$,

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

(i) Sin $\theta$ refers to a particular ratio. It is not sin multiplied by q.

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

(iii) In right angled triangles the 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.
