Can you help me with trigonometry concept

Trigonometry is a branch of mathematics that studies the relationships between the sides and angles of triangles, particularly right-angled triangles. Its core functions are sine ($\sin$), cosine ($\cos$), and tangent ($\tan$), which relate the angles of a right triangle to the ratios of its side lengths (often remembered by SOH CAH TOA). These functions allow us to calculate unknown side lengths or angle measures when some information about the triangle is known.
