Trigonometry Chart for Students and Children

What is Trigonometry Chart?

First of all, trigonometry refers to a branch of mathematics that focuses on relationships between side lengths and angles of a triangle. Furthermore, a trigonometry chart is a chart that comprises of various trigonometric ratios that have an interrelation with each other. Above all, these trigonometric ratios are- cosine, sine, tangent, secant, cosecant, and cotangent. In short form, one can write these ratios as cos, sin, tan, sec, cos, and cot.

The trigonometry chart provides values of standard trigonometric angles which includes 0°, 30°, 45°, 60°, and 90°. Furthermore, these values consist of a high amount of importance and significance in comparison to others. This is because the most important problems make use of these ratios.

How to Create a Trigonometry Chart

The various steps to draw a trigonometry chart are as follows:

Step 1: Create a tabular column with important angles like 0°, 30°, 45°, 60°, and 90°. Afterwards, one must write all trigonometric functions in the first column. These trigonometric functions are cos, sin, tan, sec, cos, and cot.

Step 2: One must determine the value of sin. Furthermore, in order to determine, one must divide the values of 0, 1, 2, 3, and 4 and then derive the square root.

Step 3: One must determine the cosine value of the necessary angle. Furthermore, the values of cos are opposite in tabular form to that of sin angles. Hence, whatever value of sin (0-x) degree may be, it will be the same as cos (90-x) degree’s value. In order to find out the value of cos, it must be divided by 4 in the opposite order of sin. Afterwards, one must take the square root.

Step 4: In this step, one must calculate the tangent value of the angle under consideration. Furthermore, the angle is equal to sin and its division takes place by cosine. Moreover, tan x = sin x.cos x.

Step 5: Estimate the value of cot. Moreover, one can determine the value of cot by all the tan’s inverse values. Therefore, the cot’s value turns out to be 1/tan for every value. This is because, cot x = cos x.sin x.

Step 6: Here, one should determine the value of cosecant with respect to the necessary angle. Furthermore, the value of cosec on any angle happens to be the inverse of sin on that specific angle.

Step 7: Finally, in this last step, one must find out the value of sec. Furthermore, the sec’s value on any angle is the cos’s inverse on that specific angle.

How can Trigonometry Chart help you in studies?

The trigonometrical ratios values of standard angles are certainly crucial in dealing with the trigonometrical problems. Therefore, it is very important for students to memorize and remember the value of the trigonometrical ratios of various angles.

The trigonometry chart is quite useful in a number of areas. This table is significant for engineering, science, and navigation. Furthermore, experts made use of this chart in the pre-digital era before the pocket calculators came into existence. Moreover, the chart facilitated the development of the first mechanical computing devices. Another important application of this particular chart is in the Fast Fourier Transform (FFT) algorithms.

Remembering the trigonometry chart will help students in various ways in the field of mathematics. Moreover, remembering this chart is not a difficult task. Dealing with various functions of trigonometry will become easy with the use of the trigonometry chart.
