Answer:
-2x cos x + 2 sin x + C
Step-by-step explanation:
∫ (2x sin x) dx
If u = 2x, then du = 2 dx.
If dv = sin dx, then v = -cos x.
∫ u dv = uv − ∫ v du
= 2x (-cos x) − ∫ (-cos x) (2 dx)
= -2x cos x + 2 ∫ cos x dx
= -2x cos x + 2 sin x + C
There is a 0% chance of selecting either of those letters as they do not appear in the work BULLDOG.
Answer:
2400
Step-by-step explanation:
using simple ratio
we have Account A : account B as
