Nilai x yang memenuhi persamaan cos x = cos 110 derajat adalah …

✅ Jawaban:

Nilai x x x yang memenuhi persamaan cos x = cos 110 ∘ cosine x equals cosine 110 raised to the composed with power c o s x = c o s 1 1 0 ∘ dapat ditentukan menggunakan rumus persamaan trigonometri untuk fungsi kosinus: x = α + k ⋅ 360 ∘ atau x = − α + k ⋅ 360 ∘ x equals alpha plus k center dot 360 raised to the composed with power space atau space x equals negative alpha plus k center dot 360 raised to the composed with power x = α + k ⋅ 3 6 0 ∘ a t a u x = − α + k ⋅ 3 6 0 ∘

Dengan α = 110 ∘ alpha equals 110 raised to the composed with power α = 1 1 0 ∘ dan k k k adalah bilangan bulat, maka:

Kesimpulan: Jika rentang yang diminta adalah 0 ∘ ≤ x ≤ 360 ∘ 0 raised to the composed with power is less than or equal to x is less than or equal to 360 raised to the composed with power 0 ∘ ≤ x ≤ 3 6 0 ∘ , maka nilai x x x yang memenuhi adalah 110 ∘ 110 raised to the composed with power 1 1 0 ∘ dan 250 ∘ 250 raised to the composed with power 2 5 0 ∘ .
