x-xcosxsinx-x cosxdx
We can simplify the expression by factoring out x in the numerator and denominator:
(x(1-cosx))/(sinx(1-cosx))dx
Now we can cancel out the (1-cosx) terms:
x/sinx dx
Using substitution, we can let u = sinx and du = cosx dx:
∫x/u du
Integrating, we get:
x ln|u| + C
Substituting back in for u, we get the final answer:
x ln|sinx| + C
