Study Notes
Menghitung Nilai sin(θ)
- Jika cos(θ) = 3/5, maka kita dapat menghitung nilai sin(θ) menggunakan identitas Pythagoras: sin²(θ) + cos²(θ) = 1.
- Substitusi nilai cos(θ) = 3/5 ke dalam identitas di atas, maka: sin²(θ) + (3/5)² = 1.
- Dengan demikian, kita dapat menghitung nilai sin(θ) yaitu: sin(θ) = ±√(1 - (3/5)²).
This quiz tests your understanding of trigonometric functions by asking you to find the value of sin(θ) when the value of cos(θ) is given. It provides a scenario where cos(θ) = 3/5 and asks for the value of sin(θ).
