Trigonometry is a branch of mathematics that deals with the study of triangles and the relationships between their sides and angles.
A trigonometric function is a mathematical function that relates the angles of a triangle to the lengths of its sides, such as sine, cosine, and tangent.
To solve a trigonometry problem, you will need to use the given information about the sides and angles of a triangle to apply the appropriate trigonometric function and find the missing value.
Trigonometry is used in various fields such as engineering, physics, architecture, and navigation, to name a few. It is also helpful in solving real-life problems involving angles and distances.
To improve your understanding of trigonometry, it is important to practice solving different types of problems and familiarize yourself with the various trigonometric identities and their applications. You can also seek help from a tutor or join a study group to reinforce your learning.
