This is the course page of Trigonometry, Functions and Limits taught at High school level (corresponding to class 11 and 12 of Indian schools). Lecture notes/Problems will be posted in PDF format on weekly basis. If you are reading the notes on your own, you may have to fill in a lot of details. The purpose of these notes is not to be comprehensive, but to keep a log of ideas/problems discussed in the classroom. The best these notes can do is supplement a good textbook (see references below).

Typo / corrections

1. line 5, page 1 of week 3 solutions has to be "=-(-tan(45))" instead of "=-(-cot(45))". It makes no difference to the answer although. (Thanks to Abhay Rangan for pointing it out)

2. Answer for the penultimate problem on page 8 of week 9 handout should have been: "If fog is bijective then f is injective and g is surjective" instead of "fog is bijective when f is injective and g is surjective".

3. In lecture 8, functions-2, problem 2, we need to specify that $a\in A$ although it is implicit in the statement $f(a)=a$ (Thanks to Akshara Ravishankar for pointing it out)

4. In lecture 26, statement of problem 8 has been rectified. (Thanks to Akshara Ravishankar)
