Course AIMS
In this course, the basic concepts of limits, differentiation and integration are introduced. Applications of differential and integral calculus are included. In addition, the course also covers topics on complex numbers, vectors and matrices. It aims to prepare the first year engineering students for further courses in engineering disciplines and more advanced mathematics in year 2.
This course aims to equip you with
- Mathematical knowledge and analytical skills so that you are able to apply techniques of advanced calculus (along with their existing mathematical skills) to solve engineering or scientific problems whenever applicable;
- Mathematical reading skills so that you can read and understand related mathematical content in the basic and popular scientific and engineering literature; and
- Mathematical communication skills so that you can effectively and rigorously present your mathematical ideas to mathematicians, scientists and engineers.
Intended Learning Outcomes
By the end of this course, you (as a student) would be able to:
- Evaluate product, quotient, power and roots of complex numbers.
- Use vector operators (dot product and cross product) to solve simple mechanics and geometry problems (e.g. find work done, moment, equations for planes, distance form a point to a plane etc.).
- Evaluate matrix determinants and use Cramer’s rule to solve simultaneous equations
- Use limit to determine if a function is continuous.
- Evaluate the derivatives of simple functions from the definition.
- Evaluate the derivatives of more complicated functions by using rules of differentiation (e.g. product rule and chain rule).
- Use the derivatives to establish linear approximations, estimate changes and solve nonlinear equations (by Newton’s method).
- Use the derivatives to assist in curve sketching and solving optimization problems.
- Evaluate integrals by using integration formulae, rules of algebra and substitution techniques.
- Evaluate more complicated integrals by using “integration by parts”, “trigonometric substitutions”, “partial fractions”, “reduction formulae” and special techniques for integrands involving quadratic or trigonometric expressions.
- Evaluate definite integrals by using trapezium & Simpson’s rules and perform error analysis.
- Evaluate improper integrals of the first, second & third kinds, and test for convergence.
- Interpret the meaning of integration by using the concept of Riemann sum.
- Use integration to find areas between curves (by dividing into vertical or horizontal strips) and volumes of solids (slicing & cylindrical shells methods).
- Use integration to find volumes of solids of revolution (slicing & cylindrical shells methods).
- Use integration to find lengths of plane curves and areas of surfaces of revolution.
Use mean value theorem, fundamental theorem of calculus and Leibniz’s rule to evaluate expressions involving differentiation and integration.
