Could anyone give me the List of équations in trigonometry chapter that needs to je remmembered
Your first source would be your textbook.
Perhaps your teacher gave you a handout of such equations.
You can always google "trig equations" or "trig equations worksheet"
There would be an infinite number of such equations.
Here is just one such worksheet

That should keep you busy for a while.
Try the questions before looking at the solutions.
Sure! In trigonometry, there are several important equations that you should remember. These equations are fundamental to solving problems involving angles, distances, and relationships between different parts of triangles. Here are some key equations:
1. Pythagorean Identity: This equation relates the three sides of a right triangle. It is given by: a^2 + b^2 = c^2, where "a" and "b" are the lengths of the legs of the right triangle, and "c" is the length of the hypotenuse.
2. Sine Function: sin(theta) = opposite/hypotenuse. This equation relates the angle "theta" in a right triangle to the ratio of the length of the side opposite the angle to the length of the hypotenuse.
3. Cosine Function: cos(theta) = adjacent/hypotenuse. This equation relates the angle "theta" in a right triangle to the ratio of the length of the side adjacent to the angle to the length of the hypotenuse.
4. Tangent Function: tan(theta) = opposite/adjacent. This equation relates the angle "theta" in a right triangle to the ratio of the length of the side opposite the angle to the length of the side adjacent to the angle.
5. Reciprocal Relationships: In addition to the above equations, there are reciprocal relationships among the trigonometric functions. For example, sin(theta) = 1/csc(theta), cos(theta) = 1/sec(theta), and tan(theta) = 1/cot(theta).
Remembering these fundamental equations will provide a strong foundation for solving trigonometry problems. Additionally, understanding how these equations are derived and how they relate to the properties of triangles can help in applying them effectively to various scenarios.
