SOH CAH TOA is a mnemonic device used in trigonometry to remember the relationships between the sides and angles of right-angled triangles. It's an essential tool for solving problems involving triangles in mathematics and real-world applications.
• The mnemonic stands for Sine (SOH), Cosine (CAH), and Tangent (TOA), representing the three main trigonometric ratios.
• These ratios relate the angles of a right-angled triangle to the lengths of its sides.
• Understanding and applying SOH CAH TOA is crucial for students learning trigonometry and for professionals in fields like engineering and physics.
• The formulas can be used to calculate unknown angles or side lengths in right-angled triangles when other measurements are known.
