Frequently Asked Questions

Essential functions include trigonometric functions (sin, cos, tan), logarithmic functions (log, ln), exponential functions, square root and power functions, statistical functions (mean, standard deviation), and the ability to solve equations and perform matrix operations (if applicable to your syllabus).
Most scientific calculators have a built-in equation solver function. Access it (usually through the MODE or MENU button), select the quadratic equation option, and input the coefficients (a, b, c) of your equation. The calculator will then display the solutions (roots) for x.
Yes, calculators can quickly compute mean, median, mode, standard deviation, and variance. Enter your data set into the calculators statistics mode, and then use the appropriate functions to calculate the desired statistical measures.
Look for a DRG or MODE button on your calculator. Press it repeatedly until you see DEG (degrees) or RAD (radians) displayed. Select the appropriate mode for your calculation.
Absolutely! After solving a problem manually, use the calculator to verify your answer. For example, substitute your solution back into the original equation to see if it holds true. This is especially useful for algebra and trigonometry problems.
Ensure your calculator is in the correct mode (degrees or radians). Use the sin, cos, and tan functions to find trigonometric ratios. Use the inverse trigonometric functions (sin⁻¹, cos⁻¹, tan⁻¹) to find angles when given the ratios.
Most calculators have a dedicated percentage (%) button. To find a percentage of a number, multiply the number by the percentage and then press the % button. For example, to find 20% of 150, enter 150 * 20 %.
Learn how to use the calculators memory functions (M+, M-, MR, MC) to store intermediate results and avoid re-entering values. Also, practice using the ANS (answer) button to use the previous result in your next calculation.
Immediately raise your hand and inform the invigilator. They will usually provide a replacement calculator, if available. Its also a good idea to bring a spare calculator to the exam as a backup.
