Differential and integral calculus are essential for physical, life and economic sciences.Students credited with this module will have a firm understanding of the limit, continuity at a point,differentiation and integration, together with a background in the basic techniques and some appli-cations of Calculus.2.1.1 Learning Assumptions: The learning is based on the assumption that students arealready competent in terms of the following outcomes or areas of learning and must:Have a Senior Certificate or equivalent qualification (as required) for further study.Have obtained an NQF/HEQF Level equivalent to 4 with the ability to:Be able to learn from predominantly written material in the language of tuitionTake responsibility for their own progress and independently adjust to the learningenvironmentHave basic computer skills like using a mouse, keyboard and windows featuresDemonstrate an understanding of the most current topics in mathematics includingFunctionsThe ability to algebraically manipulate real numbers and solve equations.An ability to sketch graphs and find equations from these graphs.Substantive knowledge about basic trigonometryKnowledge about the following mathematical concepts: absolute values, partialfractions and inequalities.Recognition of prior learning will take place in accordance with the institution’s policyand guidelines. Recognition takes place, where prior learning corresponds to the re-quired NQF-HEQF level and in terms of applied competencies relevant to the contentand outcomes of the qualification, at the discretion of the department.2.1.2 Range statement for the module: The techniques selected involve polynomial, ratio-nal, trigonometric, exponential and logarithmic functions and their composites.
