Learn Trigonometry Table in 3 minutes | Best Trick To Remember Trigonometric Table
Trigonometric values are very difficult to learn as it has a number of values in it. I Made an effort to make you learn the trigonometric table using one of the best trick you will ever found on youtube.
In simple words, the Trigonometric Table is a collection of the values of trigonometric ratios for the commonly used standard angles including 0°, 30°, 45°, 60°, 90°. Sometimes it is also used to find the values for other angles like 180°, 270°, and 360° in the form of a table. Various patterns exist within trigonometric ratios and between their corresponding angles. Therefore, it is easy to predict the values of the trigo table and also use the table as a reference to calculate trigonometric values for other non-standard angles. The various trigonometric functions in Mathematics are sine function, cosine function, tan function, cot function, sec function, and cosec function.
Before beginning, let us try to recall the trigonometric formulas listed below.
sinx=cos(90∘−x)
cosx=sin(90∘−x)
tanx=cot(90∘−x)
cotx=tan(90∘−x)
secx=cosec(90∘−x)
cosecx=sec(90∘−x)
1sinx=cosecx
1cosx=secx
1tanx=cotx
Trigonometric Values
Trigonometry is the study of the relationship between the sides of a triangle (right-angled triangle) and its angles. The term trigonometric value is used to collectively define values of different ratios, such as sine, cosine, tangent, secant, cotangent, and cosecant in a trigonometric table. Every trigonometric ratio is connected to the sides of a right-angle triangle and the trigonometric values are found using these ratios.
Standard Angle Trigonometry Tables
The trigonometry ratio table is essentially a tabular collection of values for trigonometric functions of different conventional angles such as 0°, 30°, 45°, 60°, and 90°, as well as unusual angles such as 180°, 270°, and 360°. Because of the patterns that exist within trigonometric ratios and even between angles, it is simple to anticipate the values of the trig ratios in a trigonometric table and use the table as a reference to compute trigonometric values for different other angles.
Trigonometric ratios – sine, cosine, tangent, cosecant, secant, and cotangent – are listed in the table. Sin, cos, tan, cosec, sec, and cot are the abbreviations for these ratios. The values of the trigonometric ratios of these standard angles are best remembered.
