PS another trick is to set ##u = \frac x L## to see that the answer is independent of ##L##. That simplifies the integral and is...

Hello so the correction i made was that i changed $$\frac{1}{L} \left[ x - \frac{L}{2\pi} \sin\left(\frac{2\pi x}{L}\right)...

apologies sin^2(x)=0.1 or sin^2(x)=0.19 , a very narrow slice, and 0.19 is a bigger width

I have recalculated the integrals and now i have that the probability of finding the particle at the said point is 0.19 ?

You can't let ##L## pop in and out in the calculation! Look at the evaluation again..
