Step 1

Halo semuanya! Mari kita periksa apakah pernyataan integral ini benar atau salah. Kita diberikan fungsi integral dua x ditambah enam sin x de x.

Verifikasi Integral

$$\int (2x + 6 \sin x) \, dx = 2x^2 - 6 \cos x + C$$
2
Step 2

Mari kita hitung integralnya secara bertahap. Ingat sifat linearitas integral, kita bisa memisahnya menjadi dua bagian.

$$\int 2x \, dx + \int 6 \sin x \, dx$$
3
Step 3

Pertama, mari kita selesaikan integral dari dua x menggunakan aturan pangkat.

1. Integral Aljabar

$$\int 2x \, dx = 2 \cdot \frac{x^{1+1}}{1+1}$$
4
Step 4

Dua x pangkat satu ditambah satu per dua menjadi dua per dua x kuadrat, yang disederhanakan menjadi x kuadrat.

5
Step 5

Sekarang perhatikan hasil pada soal. Di sana tertulis dua x kuadrat. Ini sudah menunjukkan adanya perbedaan.
