Question

1. ∫4 sin x dx ??
2. ∫(x-cos x) dx??

Answer 1

Verified answer

Integral sin x dx = - cos x + c
integral cos x dx = sin x + c

1. 4x - cos x + c
2. 1/2 x2 - sin x + c

Answer 2

Integral.

Nomor 1
∫ 4 sin x dx
= 4 ∫ sin x dx = -4 cos x + C

Nomor 2
∫ (x - cos x) dx
= x¹⁺¹ / (1 + 1) - sin x + C = 1/2 x² - sin x + C
