How to learn trigonometry table easily with the triangle?
Answers
Easy way to learn trigonometry table easily with the triangle is given below:
Explanation:
Trigonometry is a piece of math. It works with angles and sides of a triangle. The main tasks in trigonometry is the calculation of trigonometric ratios, known as cosine, sine and tangent of the angle in a triangle.
Given below the steps to be taken to prepare the table:
1. Firstly create a table: Draw the table with 6 columns and 6 rows. In the 1st row, write the trigonometric ratios as sine, cosine, tangent, cosecant, secant, and cotangent and in the 1st column write the angles which are used in trigonometry 0°, 30°, 45°, 60°, 90°.
2. Fill the values of sine in the column: We will use √x/2 to fill the entries in the column. The value of x have to be that of the angle which has been listed on table. Use the formula for the calculation of sine values as of 0°, 30°, 45°, 60°, and 90° then we will write down those values into our table.
To get an idea, we will see the sine column for the value of (sin 0°), we will put the x equal to 0 ( zero ) and then putting in √x/2. This will provide us √0/2, which is simplified as 0/2 and then we get 0.
3. Placing entries of sine column in reverse order in the cosine column: If we speak according to math sin x° = cos (90 - x)° for any value of x.
Once the values are placed in the cos column that should be 1, √3/2, 1/√2, ½, and 0.
