The easiest maths subjects you can do (assuming you don't want to do maths in later years) is life science maths. The requirement for these is HSC mathematics. Below are the "easiest" maths units for first year which are provided in the faculty of science handbook.
Semester 1
MATH1011 Life Sciences Calculus
Credit points: 3 Session: Semester 1,Summer Main Classes: Two 1 hour lectures and one 1 hour tutorial per week. Prohibitions: MATH1111, MATH1001, MATH1901, MATH1906 Assumed knowledge: HSC Mathematics Assessment: One 1.5 hour examination, assignments and quizzes.
This unit is designed to provide calculus for students of the life sciences who do not intend to undertake higher year mathematics and statistics. It includes the fitting of data to various functions, introduces finite difference methods, and it demonstrates the use of calculus in optimisation problems. It extends differential calculus to functions of two variables and develops integral calculus, including the definite integral and multiple integrals.
MATH1015 Life Science Statistics
Credit points: 3 Session: Semester 1 Classes: Two 1 hour lectures and one 1 hour tutorial per week. Prohibitions: MATH1005, MATH1905, STAT1021, STAT1022, ECMT Junior units of study. Assumed knowledge: HSC Mathematics Assessment: One 1.5 hour examination, assignments and quizzes.
MATH1015 is designed to provide a thorough preparation in statistics for students of the Life Sciences.It offers a comprehensive introduction to data analysis, probability and sampling, inference including t-tests, confidence intervals and chi-squared goodness of fit tests. There are comprehensive details of this unit of study in the Junior Mathematics Handbook distributed at the time of enrolment.
Semester 2
MATH1013 Differential and Difference Equations
Credit points: 3 Session: Semester 2 Classes: Two 1 hour lectures and one 1 hour tutorial per week. Prohibitions: MATH1003, MATH1903, MATH1907 Assumed knowledge: HSC Mathematics or MATH1111 Assessment: One 1.5 hour examination, assignments and quizzes.
MATH1013 is designed to provide the theory of difference and differential equations for students of the life sciences who do not intend to undertake higher year mathematics and statistics. This unit of study looks at the solution of equations by bisection and iteration, first and second order difference equations where chaos is met, and examples of modelling using simple first and second order differential equations.
MATH1014 Introduction to Linear Algebra
Credit points: 3 Session: Semester 2,Summer Main Classes: Two 1 hour lectures and one 1 hour tutorial per week. Prohibitions: MATH1012, MATH1002, MATH1902 Assumed knowledge: HSC Mathematics or MATH1111 Assessment: One 1.5 hour exam, assignments, quizzes
This unit is an introduction to Linear Algebra. Topics covered include vectors, systems of linear equations, matrices, eigenvalues and eigenvectors. Applications in life and technological sciences are emphasised.
