Gunakan identitas trigonometri untuk membuktikan bahwa sin²(θ) + cos²(θ) = 1.
sin²(θ) + cos²(θ) = 2
sin²(θ) + cos²(θ) = 1
sin²(θ) + cos²(θ) = 0
sin²(θ) - cos²(θ) = 1

Selesaikan persamaan trigonometri: 2sin(x) - 1 = 0.
x = π/6 + 2kπ, x = 5π/6 + 2kπ, k ∈ Z
x = π/4 + 2kπ
x = 0 + 2kπ
x = 3π/4 + 2kπ

Gambarlah grafik fungsi y = sin(x) dalam interval [0, 2π].
Grafik fungsi y = sin(x) dalam interval [0, 2π] adalah gelombang sinus yang dimulai dari (0, 0), mencapai puncak di (π/2, 1), kembali ke nol di (π), mencapai titik terendah di (3π/2, -1), dan kembali ke nol di (2π).
Grafik fungsi y = sin(x) dalam interval [0, 2π] adalah gelombang sinus yang terus meningkat tanpa batas.
Grafik fungsi y = sin(x) dalam interval [0, 2π] hanya memiliki satu titik di (π, 0).
Grafik fungsi y = sin(x) dalam interval [0, 2π] adalah garis lurus dari (0, 0) ke (2π, 0).
