Answer 2

Answer:

1/2[x - 1/2{sin(2logx)}] + c

Step-by-step explanation:

Let log(x) = t and differentiate,

1/x dx = dt

The integral becomes :

∫ sin²(t) dt = 1/2[x - sin(t)cos(t)] + c = 1/2[x - 1/2{sin(2x)}] + c = 1/2[x - 1/2{sin(2logx)}] + c

Formulae used :

• d(logx)/dx = 1/x
• ∫ sin²(x) = 1/2[x - sin(x)cos(x)]
