learn.whatIsHeading
Trigonometry studies relationships between angles and sides of triangles. Beyond right triangles, the law of sines and law of cosines handle any triangle. Trigonometric identities simplify complex expressions.
Adım Adım Kılavuz
- 1Law of Sines: a/sin(A) = b/sin(B) = c/sin(C)
- 2Law of Cosines: c² = a² + b² − 2ab×cos(C)
- 3Pythagorean identity: sin²θ + cos²θ = 1
- 4Sum formulas: sin(A+B) = sinA×cosB + cosA×sinB
