Life Science is a systematic study of living
organisms

• Botany
• Zoology
• Microbiology
• Biochemistry
• Biophysics
• Molecular and Cellular Biology

• Ecology
• Physiology
• Agricultural Science
• Biotechnology
• Biology
• Marine Biology
• etc.

To understand things better, we need to learn
math so 1LS3/1LT3 is math in context
3
Math 1LS3/1LT3 There are three sections of 1LS3
this term ALL SECTIONS COVER EXACTLY SAME
MATERIAL, WRITE SAME TESTS AND SAME FINAL EXAM
One section of 1LS3 in Winter 2013 One section
of 1LS3 in Spring 2013 (to be confirmed) Math
1LT3 will be taught in Winter 2013 Math 1LT3 in
Summer 2013 (to be confirmed)

Math 1LS3 No tutorials this week tutorials
start in the week of September 10 Attend the
lecture and tutorial section you have been
assigned to! Math Help Centre individual help
in HH104 will open around September 17 (will be
announced on the web page)
5
Math 1LS3 Fall 2012 Same web page for all
sections http//www.math.mcmaster.ca/lovric/1LS3.
html (search by Math 1LS3) also were on
facebook Check web page 2-3 times a week
6

• Whats on Math 1LS3 web page
• course outline (how your final mark will be
  calculated)
• frequently asked questions (calculator policy,
  policy on missed tests, etc.)
• solutions to all assignments and tests
• updates of marks
• information about tests, exam, announcements

7
What do I need for 1LS3? its all in the main
bookstore Textbook "Calculus for the Life
Sciences Modelling the Dynamics of Life", by F.
A. Adler and M.Lovric same as last
year Coursepack not the same as last
year Calculator McMaster standard calculator
Casio fx991
8

• Optional materials
• Students solutions manual
• Calculus Fear No More helps you review high
  school math

9

• Expectations
• come to classes and tutorials class notes
  will not be posted on internet (exception
  powerpoint slides, and whats not in the
  textbook)
• do homework as assigned on the webpage,
  practice on your own homework is not collected
  for credit
• for every hour of lecturing you need to spend
  2-3 extra hours reviewing your notes, doing
  assigned reading, solving exercises, drill, etc.

10

• Most important things
• study regularly, dont get behind or recover
  quickly if you do also, eat, sleep, exercise,
  socialize the key is balance!
• math (at this level) is lots of drill/practice
  boring but very useful background strongly
  correlated to your success in this course (so
  review now if needed)
• plan your time daily, weekly

11

• your life is your responsibility reflect on
  things, identify problems and deal with them
  immediately
• If you do not change things,
• things will not change !

12

• This course
• standard calculus stuff limit, continuity,
  derivative, integral
• calculus objects in context for instance a
  function (abstract math object) could represent a
  population of bacteria (application)
• modeling using math to study problems arising
  in life sciences
• approaches to math algebraic, numeric,
  geometric, verbal (descriptive)

13

• Lectures and tutorials
• Lectures cover important things, but cannot
  cover everything
• You will be using your textbook regularly
• You will work on assignments regularly
• Questions? ask in class send an email to your
  instructor (email contacts are on the course web
  page) and she/he will discuss it in a lecture or
  tutorial

What questions can 1LS3 help us answer ?
How do we know that dinosaurs died about 65
million years ago? How does our body process
drugs (Tylenol, alcohol, recreational drugs)?
How does math help forensic pathologists find a
location of impact (say from a bullet) from blood
splatters? An x-ray shows that a blood vessel
branches off the right coronary artery at an
angle of 78 degrees. Is there a reason for
concern?
15
What questions can 1LS3 help us answer ?

• How can we calculate the area or the volume of
  a lake (we need this need when we study
  pollutants and their effect on underwater fauna
  and flora)?
• How many people will live in Canada in 2022?
• My body mass index is 27 (above normal range).
  How much weight should I lose to make it 24
  (healthy weight)?
• Which animal has more skin, a mouse or an
  elephant?
• How fast does the blood flow in our bodies?

16
What questions can 1LT3 help us answer ?

• How can math help us understand the behaviour
  or two species sharing the same ecosystem (such
  as bacteria and amoeba, or foxes and rabbits)?
• How does a pollutant (in the air, or in a lake)
  spread from its source?
• A person tests positive for a certain medical
  condition (such as flu, cancer, or HIV). How
  likely is it that he/she actually has it?

17
What questions can 1LT3 help us answer ?
The average efficacy of an oral contraceptive
is 97.5 per year. What is the probability that a
sexually active woman who takes birth control
pills will get pregnant at least once in a 5-year
period? On average, there are 17.6 cases of
bacterial meningitis per year in Hamilton. In
February 2011, eight cases were diagnosed. How
likely is that this occurred by chance? Or, is it
a sign of an emerging epidemic?

• Why Math Matters 
• Students scores on GMAT and LSAT in relation to
  their undergraduate major more information in
  your coursepack
• ( means above average, - means below average of
  all tests)

Major LSAT GMAT Major LSAT GMAT
Math 12.8 13.3 Biology 4.0 3.3
Philosophy 8.7 11.0 Psychology 0.9 0.8
Economics 9.6 7.3 Political Sci. -1.6 0.1
Chemistry 7.6 7.5 Arts Music -.05 -1.2
English 5.6 4.1 Business -4.5 -0.8

Composite MCAT versus undergraduate major
math
20
Even if you just take a course in math (rather
than minor or major) the benefits will be there
21

• What to expect?

energy, hours of sleep, enthusiasm, money, time
spent with friends, variety of food, general
living standard
22

• What to expect?

stress, amount of work to do, number of
deadlines, time you can survive without food or
clean clothes
23

• Where do I start?
• Visit and bookmark Math 1LS3 web page, get
  familiar with it
• To warm up work on questions from assignment 0
  in your coursepack (compare with solutions on the
  course web page)
• Buy your textbooks, get organized
• Organize your time (attending classes,
  studying, exercising, sleeping, socializing,
  etc.)
