In all of the tables in this document, both the pre-2009 NQF Level and the NQF Level is shown. In the text (purpose statements, qualification rules, etc), any references to NQF Levels are to the pre-2009 levels unless specifically stated otherwise.  

This unit standard does not replace any other unit standard and is not replaced by any other unit standard. 

PURPOSE OF THE UNIT STANDARD 
This unit standard will be useful to people who aim to achieve recognition at some level in Further Education and Training or to meet the Fundamental requirement of a wide range of qualifications registered on the National Qualifications Framework.
People credited with this unit standard are able to:
  • Carry out operations on complex numbers in non-trivial cases.
  • Use complex numbers and systems to make sense of and solve non-trivial problems. 
    		•

    LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    The credit value is based on the assumption that people starting to learn towards this unit standard are competent in Mathematics and Communications at NQF level 3. 

    UNIT STANDARD RANGE 
    Range statements are provided for specific outcomes and assessment criteria as needed. 

    Specific Outcomes and Assessment Criteria: 

    SPECIFIC OUTCOME 1 
    Use complex numbers and systems to make sense of and solve non-trivial problems. 
    OUTCOME RANGE 
  • Indicate complex number solutions to equations
  • Interpret and use modulus notation with complex numbers
  • Represent complex numbers using various methods such as vector, polar and algebraic. 
    		•

    ASSESSMENT CRITERIA     

    ASSESSMENT CRITERION 1 
    1. Notation for expressing numbers and symbols is consistent with mathematical conventions. 

    ASSESSMENT CRITERION 2 
    2. Methods of calculation are appropriate to the problem types. 

    ASSESSMENT CRITERION 3 
    3. Complex numbers are represented in a various ways and in a form appropriate to the context. 

    ASSESSMENT CRITERION 4 
    4. Operations on various representations of complex numbers are consistent. 

    ASSESSMENT CRITERION 5

    ASSESSMENT CRITERION 2 
    2. Algorithms are executed appropriately in calculations. 

    ASSESSMENT CRITERION 3 
    3. Operations on various representations of complex numbers are consistent. 

    ASSESSMENT CRITERION 4 
    4. Notation for expressing numbers and symbols is consistent with mathematical conventions. 


    UNIT STANDARD ESSENTIAL EMBEDDED KNOWLEDGE 
    The following essential embedded knowledge will be assessed through assessment of the specific outcomes in terms of the stipulated assessment criteria. Candidates are unlikely to achieve all the specific outcomes, to the standards described in the assessment criteria, without knowledge of the listed embedded knowledge. This means that the possession or lack of the knowledge can be inferred directly from the quality of the candidate`s performance against the standards.
  • Number systems and real and complex numbers. 
    		•


    Critical Cross-field Outcomes (CCFO): 

    UNIT STANDARD CCFO IDENTIFYING 
  • Identify and solve problems using critical and creative thinking:
    Solving a variety of numerical problems involving complex numbers
  • Use mathematics:
    Use mathematics to analyse, describe and represent situations and to solve problems. 
    		•

    UNIT STANDARD CCFO COLLECTING 
  • Collect, analyse, organise and critically evaluate information:
    Gather, organise, evaluate and interpret information to assist in problem solving. 
    		•

    UNIT STANDARD CCFO COMMUNICATING 
  • Communicate effectively:
    Use everyday language and mathematical language to describe relationships, processes and problem solving methods. 
    		•

    PROVIDERS CURRENTLY ACCREDITED TO OFFER THIS UNIT STANDARD: 
    This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here.
