**Time and place.** Wean Hall 4623, weekdays 10:30–11:50am from 19th May 2014 to 27th June 2014.

Welcome to 21-256! This is a six-week summer course that will teach you how to use a wide range of mathematical tools from multivariate analysis. A student who completes this course with a good grade can expect to feel comfortable using the techniques they’ll need to embark upon quantitative study of phenomena in which several measurable variables are at play (e.g. in economics, business, statistics, social sciences). This course is advertised as being intended for economics and business majors, but in reality is suitable for many more.

**Homework.**

**Homework 1**(due Tuesday 20th May): Fill in the questionnaire I gave you in class.**Homework 2**(due Friday 23rd May) — solutions**Homework 3**(due Wednesday 28th May) — solutions**Homework 4**(due Monday 2nd June)**Homework 5**(due Friday 6th June)**Homework 6**(due Friday 13th June)**Homework 7**(due Monday 23rd June)**Homework 8**(due Thursday 26th June)

**Summary notes.** I have prepared a collection of (somewhat terse) summary notes on topics covered, largely void of examples:

Vectors and matrices |
Optimization |
Integration |

**Exams.**

**Exam 1**(Monday 2nd June): Vectors and matrices — sample — sample solutions**Exam 2**(Wednesday 18th June): Partial differentiation — sample — sample solutions**Exam 3**(Friday 27th June): Lagrange multipliers and integration — sample — sample solutions
