This is really easy! If you have the x and y coordinates: For example: (3; 4) Type in 3  4    Your calculator screen will then look like this: r is your hypotenuse – which is 5 and your angle made with between the y-axis and the hypotenuse is 53o  What if you have the angle and […]

Second Common Differences can be a bit complicated. The SHARP EL-535 can be very useful to help you figure out the formula and also to check whether your answers are right. Let’s do an example: You are given the pattern 3, 7, 15… On your calculator press: 1 (For stat) and then 2 for Quad […]

Enter 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 […]
