ข้อกำหนดเครื่องคิดเลข
A silent scientific calculator may be used on papers where calculators are permitted (some papers are non-calculator). It must not be graphical or programmable and must hold no stored information.
วัตถุประสงค์: Tabulate \(y\) across a range of \(x\) to locate sign changes (roots) and approximate maxima/minima.
ใช้เมื่อใด: Solving or sketching a function when you want to find where its graph crosses or turns.
ขั้นตอน
Enter the function in TABLE mode, set the start, end and step, then read where the sign of \(y\) changes or where it peaks.
ข้อควรระวังในการสอบ: Allowed on papers where a calculator is permitted; use a silent scientific calculator with no stored content and show your method.
Statistics mode (mean, SD & regression)
Scientific calculator (e.g. Casio fx-991 series)
วัตถุประสงค์: Read the mean \(\bar{x}\) and standard deviation directly, and the gradient/intercept (and \(r\)) of a linear regression for bivariate data.
ใช้เมื่อใด: Any data-handling, statistics, or required-practical analysis question.
ขั้นตอน
Enter the data in STAT mode (1-VAR or A+BX), then recall \(\bar{x}\), \(\sigma\) or the regression coefficients.
ข้อควรระวังในการสอบ: Allowed on papers where a calculator is permitted; use a silent scientific calculator with no stored content and show your method.
Carry exact values with Ans & memory
Scientific calculator (e.g. Casio fx-991 series)
วัตถุประสงค์: Keep full-precision intermediate values to avoid rounding errors.
ใช้เมื่อใด: Multi-step calculations where premature rounding loses the final accuracy mark.
ขั้นตอน
Use Ans, STO/RCL or the M+ memory to reuse the unrounded result of each step; round only the final answer.
ข้อควรระวังในการสอบ: Allowed on papers where a calculator is permitted; use a silent scientific calculator with no stored content and show your method.
Equation solver — to CHECK your working
Scientific calculator (e.g. Casio fx-991 series)
วัตถุประสงค์: Use the built-in EQN/SOLVE mode to verify roots of quadratics or simultaneous equations you have already solved by algebra.
ใช้เมื่อใด: As a check only, after solving by hand.
ขั้นตอน
Enter the coefficients in EQN mode (or use SOLVE) and confirm they match your worked solution.
ข้อควรระวังในการสอบ: Allowed on papers where a calculator is permitted; use a silent scientific calculator with no stored content and show your method.
Rounding intermediate steps prematurely to 2 or 3 significant figures, especially in circular measure and multi-step trigonometry questions.
วิธีหลีกเลี่ยง: Retain intermediate calculations in exact form (e.g. surds, fractions, terms of pi) or round to at least 4-5 significant figures. Only round your final answer to 3 significant figures (or 1 decimal place for angles in degrees).
Ignoring the word 'Hence' in multi-part questions and using a generic or starting method from scratch.
วิธีหลีกเลี่ยง: Use the result obtained in the immediately preceding part of the question. This is a strict instruction; starting a fresh method wastes time and risks losing key method marks.
Omitting the negative square root or alternative branches when solving quadratic or modulus equations.
วิธีหลีกเลี่ยง: Remember that taking the square root of both sides of an equation yields both positive and negative values (e.g., cot^2 x = k yields cot x = +/- sqrt(k)), and modulus equations require checking both positive and negative cases.
Using x instead of y or f(x) when writing down the range of a function, or confusing domain and range variables.
วิธีหลีกเลี่ยง: Define domain using x (e.g. x > a) and define range using y, f(x), or g(x) (e.g. f(x) <= b). Remember that the domain of an inverse function is identical to the range of the original function.
Calculating total distance in kinematics by directly integrating velocity across the whole interval without checking for changes in direction.
วิธีหลีกเลี่ยง: Identify any times t where velocity v = 0. If the particle changes direction within the interval, split the integration into sub-intervals, integrate each section separately, and sum their absolute values.
Using a calculator in degree mode instead of radian mode when executing calculus evaluations on trigonometric terms.
วิธีหลีกเลี่ยง: Differentiating or integrating trigonometric functions is only mathematically valid when angles are in radians. Always toggle your calculator to RADIAN mode before evaluating calculus limits.
