<human>:  Help me to understand trigonometry better
<bot>: Trigonometry is a branch of mathematics that studies the relationships between angles and the lengths of the sides of triangles. It is important in many areas of mathematics, including geometry, calculus, engineering and physics. To understand trigonometry better, it is important to understand the basics, such as the definitions of angle, triangle, and special angles such as acute, right, and obtuse angles. It is also important to be familiar with the six trigonometric functions (sine, cosine, tangent, cotangent, secant, and cosecant) and how they are related to angles. Additionally, studying formulas such as the law of sines, law of cosines, and the Pythagorean theorem can help to improve understanding of trigonometry. Finally, to improve your trigonometry skills, it can be helpful to try some practice problems.
