UNA trigonometry table lists the values of trigonometric functions (sine, cosine, tangent, etc.) for various angles. These tables are useful for solving problems in mathematics, physics, and engineering, especially those involving triangles and periodic functions.
𝐭𝐫𝐢𝐜𝐤:-
we can find their value, it is a simple trick.
1)You have to make a table like this or you have to write 0,1,2,3,4 or divide all the numbers with four.And then put squareroot on these numbers. From this we get the value of 𝒔𝒊𝒏 𝒕𝒉𝒆𝒕𝒂 .
2) now if we write these values from opposite side , then we get the value of𝐜𝐨𝐬 𝐭𝐡𝐞𝐭𝐚 .
3) WKT,𝐭𝐚𝐧 𝐭𝐡𝐞𝐭𝐚 is the ratio of sine theta and cos theta .
4) if we write the value of tan theta from opposite side , then we get the value of 𝐜𝐨𝐭 𝐭𝐡𝐞𝐭𝐚. (Bcz WKT. Cot theta is the reciprocal of tan theta).
5) if we reciprocal all the value of cos theta , then we get the value of 𝐬𝐞𝐜 𝐭𝐡𝐞𝐭𝐚 .
6) And then if we write the value of sec theta from opposite side, we get the value of 𝐜𝐨𝐬𝐞𝐜 𝐭𝐡𝐞𝐭𝐚.📚
