Great explanation of finding the integral with u substitution. I still get slightly confused when (in your example) we have cos 3x ÷ 1/3 cos 3x as I immediately think we can divide without moving the constant (so 3 would be my answer in this case at that point)

I'm thanking you for this video and it was not what if there was a difference between the angle for example the allowance of cos (3 ×) sin (5 ×)
