You had me scratching my head - questioning my understanding of the sin function for a few minutes until you corrected yourself.

At 6:25, sin(n pi) = 0 NOT pi/2. Fortunately, sin(x) and cos(x) are interchangeable in the original equation.

I solve in my head, and take a right answer

I cannot believe you left such an error in after realising it. Shocking. We all make mistakes but NO!
