CAS Mathematics 2.2 Demonstrate an understanding of calculus methods
Key tips
- Practise using
notations. - The use of the correct notation is expected.
- You will be expected to interpret your solutions in context, using sensible rounding.
- Computer Algebraic Systems (CAS) technology may be used.
- Practise differentiation and integration of terms.
- Check that you answer the question that is asked and relate your answer to the context of the problem.
- You must choose the appropriate process, show clear evidence of correct differentiation or integration, and use this function to answer the question.
- When using calculators, you must show the derived and integrated solutions and any equation that you needed to form.
- Remember when you are finding an area below the x-axis, the integral will be negative. The area is positive. The negative sign just tells you that the area is below the axis.
- When finding area under a graph you need to sketch a graph first, if one is not given. If the x-axis divides the area into separate sections above and below the axis, you will find the integrals of each part separately. Make the value of each area positive, and add them together.
