Administrivia – contd. Grading: Midterm: 15% Final: 25% Lab/assignments: 60% Grades: will be on online (will be linked from class homepage). 1/16/2019 Math/CSE 1560, Winter 2011

Administrivia – contd. Missed labs: If you have a valid medical reason and proper documentation, the credit will be moved to other labs If you have some other emergency, the credit will be moved at the instructor’s discretion, or the assignment will be assigned zero. Same policy for midterm, but credit will be shifted to final examination. 1/16/2019 Math/CSE 1560, Winter 2011

Course objectives Familiarity with the Maple environment. Ability to "code" solutions to simple problems in Maple. Introduction to computer programming, including encapsulation of functionality into procedures and functions. Elements of efficient programming principles, simple algorithm design, debugging programs. 1/16/2019 Math/CSE 1560, Winter 2011

What I expect from you Coming to class on time Your cellular phone(s) should be switched off or in silent mode. Active interest in the course and subject material Being prepared for the labs and assignments 1/16/2019 Math/CSE 1560, Winter 2011

Labs There will be 3-hour labs, every week. Due to the class size, there are 3 sections, Tues, Thurs, Fri 2:30-5:30 pm, all at the Gauss lab, Ross S 100. Getting access to the Lab: The Gauss Lab has a website (link on class web page), containing information about card access. 1/16/2019 Math/CSE 1560, Winter 2011

Labs: contd. Laboratory assignments are crucial to this course Assignments will be completed and submitted in the lab. Math moodle site (http://webct.math.yorku.ca) has one entry for each lab session. You will login to the session you enrolled in. Assignments are individual. You cannot solicit or obtain help from friends, the Internet, or other electronic resources. Academic dishonesty will be dealt with very seriously 1/16/2019 Math/CSE 1560, Winter 2011

Important!! You should do these ASAP: 1. activate AML account through Instructions from the Math software support group You should do these ASAP: 1. activate AML account through Passport York (http://mms.yorku.ca) 2. pickup prox-card from William Small center 1/16/2019 Math/CSE 1560, Winter 2011

What is Maple? A very powerful calculator! Symbolic computation (CAS,…) Interactive programming and debugging High-quality plots Useful for many branches of Mathematics 1/16/2019 Math/CSE 1560, Winter 2011

Computer programming Computer programs are sequences of commands that implement a solution conceived for a problem. Popular languages: Java, C/C++, Visual Basic. Different languages provide different command sets/ (and expressiveness) translate into binary strings that can be executed by the hardware. 1/16/2019 Math/CSE 1560, Winter 2011

Maple vs other languages Different workflow Interactive development Different manner of execution of code Extent of built-in functions Objective/audience 1/16/2019 Math/CSE 1560, Winter 2011

Maple versions and UI’s Different versions Different user interfaces in different platforms Separating the looks from the functionality Latest version 1/16/2019 Math/CSE 1560, Winter 2011
