Booklets/Notes/Assignments are typed here on this website and their PDFs will be made available soon.

 It is during our darkest moments that we must focus to see the light.

HOTS Questions discussed in this video:

1. \int\frac{1}{\sin{x}+\sin{2}x}dx=\frac{1}{6}\log{|}1-\cos{x}|+\frac{1}{2}\log{|}1+\cos{x}|-\frac{2}{3}\log{|}1+2\cos{x}|+C

2. \int{\frac{\sin{x}}{\sin{4}x}dx=-\frac{1}{8}\log{\left|\frac{1+\sin{x}}{1-\sin{x}}\right|}}+\frac{1}{4\sqrt2}\log{\left|\frac{1+\sqrt2\sin{x}}{1-\sqrt2\sin{x}}\right|}+C
