Question

Explain me this table in detail :)



$\boxed{\begin{array}{| c | c | c | c | c | c |}\\ \bf{∠ A } & \bf{ 0° } & \bf{30°} & \bf{45°} & \bf{60°} & \bf{90°}\\\\ \textsf{Sin\;∅} & 0 & \cfrac{1}{2} & \cfrac{1}{\sqrt{2}} & \cfrac{\sqrt{3}}{2} & 1 \\\\ \textsf{cos\;∅} & 1 & \cfrac{\sqrt{3}}{2} & \cfrac{1}{\sqrt{2}} & \cfrac{1}{2} & 0 \\\\ \textsf{tan\;∅} & 0 &\cfrac{1}{\sqrt{2}} & 1 & \sqrt{3} & \sf{N.D.} \\\\ \textsf{cosec\;∅} &\sf{N.D.}& 2 & \sqrt{2} & \cfrac{2}{\sqrt{3}} & 1 \\\\ \textsf{sec\;∅} & 1 & \cfrac{2}{\sqrt{3}} & \sqrt{2} & 2 & \sf{N.D.} \\\\ \textsf{cot\;∅} & \sf{N.D.} & \sqrt{3} & 1 & \cfrac{1}{\sqrt{3}} & 0 \\ \end{array}}$​

Answer 1

Explanation:

Trigonometry Table comprises the values of various trigonometric ratios for standard angles, like 0°, 30°, 45°, 60°, and 90°. Sine, cosine, tangent, cotangent, secant, and cosecant are the six trigonometric ratios. The trigonometry table showcases the values of these trigonometric ratios for different angles. Knowing these values can make it easier to solve various trigonometric problems.

Memorizing the trigonometry ratio table can help you solve various problems easily. So, if you are looking for trigonometry table tricks, you have come to the right place. Here we will tell you the easy way to learn trigonometry formulas for tables.

If you already know the trigonometry formulas, remembering the trigonometry ratio table will be extremely easy for you. Also, with the formulas at your fingertips, you can calculate the values yourself at any point even if you forget.

there are many different ways to remember it. search it in you tube.

this table is very very important.

hope it helps you..

thank you

Answer 2

Explanation:

In mathematics, tables of trigonometric functions are useful in a number of areas. Before the existence of pocket calculators, trigonometric tables were essential for navigation, science and engineering

Trigonometric ratios table helps to find the values of trigonometric standard angles such as 0°, 30°, 45°, 60° and 90°. It consists of trigonometric ratios – sine, cosine, tangent, cosecant, secant, cotangent. These ratios can be written in short as sin, cos, tan, cosec, sec and cot.
