Jinsi ya kukokotoa Trigonometry
Trigonometry ni nini?
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.
Mwongozo wa Hatua kwa Hatua
- 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
Mifano Iliyotatuliwa
Ingizo
sin(30°)
Matokeo
= 0.5 · cos(60°) = 0.5 · tan(45°) = 1
