Use integration by parts to evaluate the indefinite integral
[ 2x sin(c) dx

-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

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.
