Grade 10 Maths VideosEnter the Quadratic Function using your Memory Keys For example: 0 = 2×2 + 5x – 6 Make sure you are in Normal mode by pressing 0. We know that a = 2; b = 5 and c = -6. We need to store this in the calculator. So we press 2 . Now store b so type […]

To prove the CAST Diagram On your SHARP EL535 calculator press . Then type in . For X_Start: type in 90 and . For X_Step: type in 15 and . Look at the answers between -90 and 0 – are they all positive or all negative? They are all negative: therefore sin is negative between […]
Binary numbers are based on the concept of ones and zeros or something similar to on and off. The base used to count in binary number is 2 and the one and zero says whether that 2 is on or off. The position of the one or zero in the binary number tells you to […]
This question was submitted by Nonhle Remember that when you are solving for x in a linear equation (that means that x does not have any exponents) you need to take all the numbers to one side and all the x’s to the other side. For example: Solve for x: 4x + 5 = 7 […]
Calculate compound interest Remember that compound interest is interest that is added to the principal amount at the end of each period. The formula to calculate compound interest: Where: FV = Future value PV = Present value i = Effective interest rate n = Number of periods The grade 12 CAPS syllabus requires learners to […]
Dear Yasodha Rani, There are so many places to use geometry in real life. There are many places that analytical geometry is used in every day life but Euclidean Geometry is used even more!! I’m sure you can think of the basic examples such as area and perimeter of the spaces in and around your […]
This question was posted by Siboniso How do we find constraints in linear programming? Thanks for the question Siboniso, There are two different kinds of questions that involve finding constraints. The first comes directly from the diagram. In this case it is a simple matter of finding the equation of the straight line using the […]

Question posted by Sihawukele An arithmetic sequence is a linear sequence – that means it has a constant difference (d). The pattern is that you add or subtract the same amount from the previous term to get to the next term. For example 2 5 8 11… What we are adding every time is 3: […]
This question was submitted by Tebugo The first thing to check for is if there are any common factors on the top and bottom. You do this by factorising the top and bottom parts of the fraction. If there are take them out and cancel them. For example – our fraction has an x in […]
