Trigonometry is the branch of mathematics which deals with triangles and the relationship between the angles and sides of triangles. Trigonometry word has been arise from the Greek word which is also having a meaning of ?3-sided measure? and it is the branch of mathematics in which we study of the relationships between sides and angles of a triangle.

Now we will see how to do trigonometry step by step?

For solving the trigonometry we have to follow some of the steps which are given below:

Step1: For solving the trigonometry, it is necessary to know about the trigonometry function. A trigonometric function of an angle is denoted as the ratio of two of the sides of a right triangle which is used to have that angle; the sine, cosine, tangent, cotangent, secant, and cosecant and the trigonometric function is also known as circular function.

Step2: let we have a triangle then we have to put one angle in the triangle which is other than the right angle.

Step3: Then after we will measure the side of a triangle which is opposite to the angle and the length.

Step4: ?After applying all the above process, we will measure the length of the side which is connecting the angle to the right angle.

Step5: Then after we have to divide the side length of opposite angle to the side adjacent angle.

A?trigonometric equation?is one of the mathematical equation which is having one or all of the six functions sin, cos, tan, cot, sec, and cosec.

Now we will see how trigonometric equations?solve with the help of example.

In first step we will see all the number cab be substituted for the values in the equation to make the equation true.

Step2: Now we will calculate for the value of function.

Step3: Then we have to find the angle of a triangle.

Step4: After calculating the angles now we will measure for the variable in a triangle.

If we apply all these steps properly then we can easily solve the trigonometric equation.

Suppose we have an acute triangle and one angle is given and length of one side is also given then,

We will start it with angles.

As P= 46?

And as shown in the figure R= 90 ? because we know that one angle of acute triangle is 90 degree than we can easily find out Q which will be 44 ?.

Now we will apply all the above steps so that we can easily get the solution:

In this given example we take unknown side in the numerator and the side which we know, we make it denominator of fraction,

I.e. numerator / denominator = p/ 12;

Here according to the above definition the variable p is unknown and the value of denominator is 12;

Now according to the second step name the function of angle,

Unknown/ known= 1/ 12= sin 46 ?

Now according to the third step we use the trigonometric table to evaluate that function,

Unknown / known= p/ 12= sin 46 ?= .719

Now we calculate the unknown side = p = 12x .719 = 8.62 inch.

When we apply all the above steps properly then we easily find the solution.
