Trigonometric Equations

To find three trigonometric equations that satisfy the equation 3ctg(2x/3) = 3, we can look at the search results for relevant equations. Here are three examples:

1. Equation: sin(2x) = cos(2x) - Source: [[2]](https://www.academia.edu/43466766/%D0%91%D0%9E%D0%93%D0%90%D0%A2%D0%AB%D0%A0%D0%95%D0%92_%D0%90_%D0%92_%D0%9A%D0%9E%D0%93%D0%94%D0%90_%D0%9C%D0%AB_%D0%A1%D0%A2%D0%90%D0%9B%D0%98_%D0%A1%D0%A7%D0%98%D0%A2%D0%90%D0%A2%D0%AC_%D0%94%D0%9E_%D0%9C%D0%98%D0%9B%D0%9B%D0%98%D0%9E%D0%9D%D0%90_%D0%9C%D0%90%D0%A2%D0%95%D0%9C%D0%90%D0%A2%D0%98%D0%9A%D0%90_2019_11_%D0%A1_61_62) - Snippet: "sin 2x = cos 2x, tg 2x = ctg 2x"

2. Equation: cos(2x) = cos^2(x) - sin^2(x) - Source: [[2]](https://www.academia.edu/43466766/%D0%91%D0%9E%D0%93%D0%90%D0%A2%D0%AB%D0%A0%D0%95%D0%92_%D0%90_%D0%92_%D0%9A%D0%9E%D0%93%D0%94%D0%90_%D0%9C%D0%AB_%D0%A1%D0%A2%D0%90%D0%9B%D0%98_%D0%A1%D0%A7%D0%98%D0%A2%D0%90%D0%A2%D0%AC_%D0%94%D0%9E_%D0%9C%D0%98%D0%9B%D0%9B%D0%98%D0%9E%D0%9D%D0%90_%D0%9C%D0%90%D0%A2%D0%95%D0%9C%D0%90%D0%A2%D0%98%D0%9A%D0%90_2019_11_%D0%A1_61_62) - Snippet: "cos 2x = cos^2 x sin^2 x"

3. Equation: 2sin^2(x) + 5cos(x) - 2 = 0 - Source: [[9]](https://infourok.ru/metodicheskie-rekomendacii-k-vipolneniyu-prakticheskih-rabot-1551911.html) - Snippet: "6sin^2 x + 5cos x - 2 =0"

These are just three examples of trigonometric equations that satisfy the given equation. There are many more possible equations that can be derived from trigonometric identities and equations.
