### Brief description

This module introduces the basic concepts of calculus, starting with a revision of functions of a real variable. The idea of a limit is developed and two special limits are established: (i) the derivative and (ii) the definite integral. Differentiation rules are derived from first principles and the fundamental theorem of calculus is used to establish the related rules for integration. We use these rules for differentiation and integration and consider some applications of these tools.

### Aims

To develop an understanding of functions, limits, differentiation and integration, and an ability to apply these tools.

### Content

1. FUNCTIONS OF A REAL VARIABLE: Graphs of elementary functions (polynominal, trigomometric, exponential, logarithm, absolute value, integer part). Periodic functions, even and odd functions. Operations on functions: addition, multiplication, division, composition.
2. LIMITS AND CONTINUITY. Limit notation. Rules for manipulation of limits. Sandwich theorem for limits, applications. Definition of continuity at a point in terms of limits. Continuity of sum, product, quotient and composite of continuous functions. Intermediate Value Theorem.
3. DIFFERENTIATION. Fermat’s difference quotient (f(x) –f(a))/(x-a). Definition of the derivative at a point. Geometric significance of the derivative. Differentiation from first principles of some elementary functions. Continuity of a differentiable function; examples of continuous non-differentiable functions. Rules for differentiation. Examples of differentiation, including logarithmic differentiation. Second order derivatives.
4. INVERSE FUNCTIONS. Definition. Trigonometric and polynomial examples. Differentiation of elementary inverse functions.
5. LOCAL MAXIMA AND MINIMA, CURVE SKETCHING. Locating the critical points of a function. Using the first derivative test to determine local maxima and minima. Points of inflexion. Graphs of rational functions, vertical asymptotes, horizontal asymptotes.
6. INTEGRATION. The Fundamental Theorem of Integral Calculus. Linearity of integration. Indefinite integrals. Methods of integration: integration by substitution, integration by parts. Definition of log x as an integral. The exponential function as the inverse of log. The hyperbolic functions. Integral of rational functions, use of partial fractions.
