<human>:  I'm having trouble understanding some trigonometry concepts. Can you help me understand the basics?
<bot>: Yes, trigonometry is the study of triangles and the relationships between their sides and angles. To understand the basics, learn the definitions of the basic trigonometric functions, such as sine, cosine and tangent. Also, familiarize yourself with various identities, such as the Pythagorean theorem and the law of sines. Finally, practice solving problems using the trigonometric functions, identities and theorems.
