For Winter 2012 Math 14 students
Click on solutions to first midterm . For each exam and quiz, I expect you to be able to compute sine and cosine of 0, pi/6, pi/4, pi/3, pi/2, pi and 3pi/2. Click on practice problems. These are for the entire quarter. For your first midterm on Wednesday March 1 use problems 1 - 7, 9de, 14. Answers, though not methods of solution, for practice problems are at the end of the document. I will not go over practice problems in class, but you can come to office hours to ask about them. Bring blanks sheets and no notes or calculator to the exam.
Click on Syllabus and homework . Answers to some of the homework problems that I wrote are at the end of the document. A few homework problems refer to pictures in homework pictures .
See above for tutoring.

The following will be used later in the quarter:

You might be interested in an old review for the material in the middle of the quarter.
Here is the parametrizations handout .
Click on simplifying some integrals .

For Winter 2012 Applied Cryptography students
Click on syllabus, handouts, homework . Click on Winzip file of files and software. Click on help with monalphabetic substitution ciphers .
For project one (the stream cipher where the keystream is a repeated keyword) the following are Winzip files for Group 1 and Group 2 and Group 3 and Group 4 and Group 5 and Group 6 .
For project two (two plaintexts XORed together) click on Winzip file of files for Project II.

For Fall 2011 Cryptography students
Please click on expectations for your final . Finals week office hours: Monday 4:35 - 5:30 and Tuesday 12:20 - 1:20. Graded homework will be in an envelope outside my office on Monday at noon.
And here are the midterm solutions .
Click on expectations for Thursday's midterm .
Click on Syllabus and handouts . Click on Homework . Click on Spartan scytale ciphertext . When you start using software to do homework on the computer (problems that start CW-) you will need to download software according to your color blue , green , orange , red , yellow . These are WinZipped files. If you are unfamiliar with extracting files from a WinZipped file then click on Help me Unzip . For MAC users, Chris Barna developed a MAC version of GP-PARI .
The program CryptoSoft.exe (aka EScrypto.exe) was written by the current student Cameron Wong, who also compiled it for MAC and Ubuntu. If you need it compiled for another operating system, then let me know.
MAC users: The above color files include versions of GP-PARI and CryptoSoft that run on Windows. For a MAC version of CryptoSoft, renamed EScrypto.exe, use the file escrypto-mac.zip contains a .dmg file which is basically a disk image. Any MAC OS X version past Snow Leopard should be able to unpack the executable and its dependencies by itself, so all you have to do it double-click it. I am not aware of a MAC version of GP-PARI. Perhaps you all can figure out how to get GP-PARI working on a MAC.
Ubuntu users: The above color files include versions of GP-PARI and CryptoSoft that run on Windows. For a Ubuntu version of CryptoSoft, renamed EScrypto.exe, use the file escrypto-ubuntu-64bit.zip contains a 64 bit executable for the Ubuntu distribution of Linux. There is a short shell script that points the OS to the two included dynamic libraries and then executes the program. You just have to to to your terminal, navigate to the folder the app was unzipped to, and then type "bash EScrypto.sh". The shell script would then take care of launching the app. Go to GP-PARI's website to download a linux version.

For students who took the AB exam and did not take Math 12:
If you took the AB exam, then you may have missed some topics that we cover in Math 12. These topics appear in later classes. Click on hyperbolic functions to read the document prepared by Professor Ostrov. Click on integrating by parts to learn a valuable integration tool or partial fractions to learn how to integrate the quotient of two polynomials (this is unfortunately somewhat involved).
