Study of triangles and trigonometric functions including sine, cosine, and tangent.
Memorizing values like \( \sin(30^{\circ}) \) or \( \cos(60^{\circ}) \) can save you time on tests. Use mnemonics like 'Some Old Horses Can Always Hear Their Owner's Approach' (SOHCAHTOA) to remember definitions. Practice with a values table and flashcards until you know the common angles by heart!
Draw a quick 'unit circle' on scratch paper to recall values during a test.
Use rhymes or songs to remember SOHCAHTOA.
