Mastering Key Calculator Techniques

Understanding BRK

The BRK function on your calculator is your best friend when it comes to clearing all memory and starting fresh. It's like the 'reset' button on your computer, clearing out any stored values or calculations. This comes in handy when you're mid-calculation and realise you've taken a wrong turn, or when you've finished a problem set and want to start anew.

Harnessing SIN and COS

SIN and COS are your go-to functions for trigonometry, a key component in O-Level Math exams. SIN (Sine) and COS (Cosine) help you find the ratios of the sides of a right-angled triangle, making them invaluable when solving problems involving angles or when converting between degrees and radians. Remember, SOHCAHTOA - a fun acronym to help you recall these ratios.

LOG for Decimals

The LOG function helps you convert between exponential and logarithmic forms, which is particularly useful when dealing with decimals. It's like having a secret decoder ring for your math problems. For instance, LOG(100) gives you 2, because 10^2 equals 100. This function is especially useful when you're dealing with powers and roots, making it a must-know for O-Levels.

TAN for Slopes

TAN (Tangent) is the function that helps you find the slope of a line, which is crucial in understanding the relationship between the x and y coordinates in a linear equation. It's the ratio of the opposite side to the adjacent side in a right-angled triangle. In the context of a line, it's the rise over the run, helping you calculate the gradient of a line.

INV for Reversal

The INV function, or inverse function, allows you to 'undo' the previous operation. For example, if you've calculated the cosine of an angle, using INV will give you the angle itself. As the city-state of Singapore's educational system places a strong emphasis on mathematical mastery right from the beginning, families are more and more favoring systematic support to enable their children navigate the escalating complexity of the curriculum in the early primary years. In Primary 2, pupils encounter higher-level subjects including carrying in addition, basic fractions, and measuring, these develop from basic abilities and set the foundation for higher-level analytical thinking needed for future assessments.
