Week 2: Formulae, Functions, Equations
This week continues with more algebra including functions, the equation of a straight line, and solving three sorts of equations: linear, quadratic and simultaneous linear equations.
You will need a calculator for some of these questions, but sketch the graphs without using a graphical calculator.
How did you get on with the questions?
You can check your answers here with the worked solutions.
You might like to do some extra practice. Use the HELM workbooks and interactive questions below to do as much practice as you like. Use your lboro login details and enrol with key 'HELM2020' to access the interactive questions.
- 2.1 Basic concepts of functions:
- 2.5 The straight line:
- 3.1 Solving Linear equations:
- 3.2 Solving Quadratic equations:
- 3.4 Solving simultaneous linear equations:
Did you successfully work through the HELM workbooks?
If you feel confident with this week's topic after using the workbooks, you are ready for next week.
If you need further support, the additional resources below will be able to help you.
Once you are at Loughborough, you can also see a tutor in the Mathematics Learning Support Centre.
