Ehime Entrance Mathematics · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

Differentiation and its applications (limits, derivatives, tangents, maxima/minima, curve sketching)

  • Compute limits of rational, radical and trigonometric-type expressions by factoring, rationalising and applying sin x / x, reaching at least 18/20 on an untimed set.

  • Differentiate polynomials, rational functions, radicals and composite functions using the product, quotient and chain rules without consulting notes.

  • Find the equation of the tangent and the normal at a given point, including points on implicitly or parametrically defined curves.

  • State the domain and differentiability conditions for every function you differentiate so no mark is lost to a missing restriction.

Your checkpoint

A 30-problem limit-and-derivative worksheet finished in 60 minutes at ≥85% accuracy, with every error rewritten and the misapplied rule named in a one-page error log.

Week 2

Differentiation and its applications (limits, derivatives, tangents, maxima/minima, curve sketching) & Integration and its applications (definite integrals, areas, volumes, equations of curves)

  • Locate maxima, minima and inflection points from the sign charts of f′ and f″, then sketch the full curve with asymptotes, intercepts and symmetry labelled.

  • Set up and solve optimisation word problems (maximum area, minimum distance, minimum surface area) and justify the answer by checking endpoints and the sign of f′.

  • Evaluate definite integrals with the fundamental theorem, substitution and integration by parts, including limits that require splitting the interval.

  • Compute the area between two curves by first finding the intersection points and then assigning the correct upper and lower function on each sub-interval.

Your checkpoint

One complete labelled curve sketch plus one optimisation problem written in full exam style (setup → derivative → sign chart → conclusion), each scored against a rubric you write yourself before attempting them.

Week 3

Integration and its applications (definite integrals, areas, volumes, equations of curves)

  • Calculate areas of regions bounded by curves, including regions that must be split at intersection points found algebraically.

  • Calculate volumes of solids of revolution about both the x-axis and the y-axis, choosing correctly between the disk/washer and shell methods.

  • Solve reverse problems in which an area or volume is given and an unknown constant in the curve equation must be determined.

  • Set up, without necessarily evaluating, the integral for a region described parametrically or implicitly, such as an ellipse or a rotated curve.

Your checkpoint

A timed 50-minute set of 6 application problems (2 area, 2 volume, 2 reverse-parameter) scored ≥80%, each accompanied by a neat sketch of the region or solid.

Week 4

Sequences, series and limits (arithmetic/geometric, recurrence relations, mathematical induction, infinite series)

  • Derive closed forms for arithmetic and geometric sequences and use them to evaluate sums written in sigma notation.

  • Solve first-order recurrence relations of the form a(n+1) = p·a(n) + q by shifting to a geometric sequence, and handle variants where the added term depends on n.

  • Write complete induction proofs for sum formulas, divisibility statements and inequalities, stating the base case, the hypothesis and the algebraic step explicitly.

  • Classify series as convergent or divergent and evaluate infinite geometric series while stating the |r| < 1 condition each time.

Your checkpoint

Two induction proofs written out in full exam style plus a 40-minute mixed sequence-and-series set scored ≥80%, both filed for later revision.

Week 5

Vectors in the plane and in space (dot products, lines, planes, geometric configuration) & Trigonometric, exponential and logarithmic functions (equations, inequalities, graphs, related rates)

  • Compute dot products in two and three dimensions and use them to find angles, perpendicularity conditions and scalar projections.

  • Write equations of lines and planes in vector, parametric and normal forms, and use them to find intersection points and distances.

  • Solve configuration problems involving position vectors: points dividing a segment in a given ratio, feet of perpendiculars, and areas or volumes obtained from vector products.

  • Solve trigonometric equations and inequalities on a stated interval by substitution and unit-circle reasoning, listing every solution in the required range.

  • Sketch, differentiate and integrate exponential and logarithmic functions while respecting the domain restriction of the logarithm.

Your checkpoint

A self-written one-page method sheet for vectors and for exponential/logarithmic functions, plus 10 solved problems drawn evenly from both domains at ≥80% accuracy.

Week 6

Trigonometric, exponential and logarithmic functions (equations, inequalities, graphs, related rates) & Probability and counting (permutations, combinations, conditional probability, expected value)

  • Solve related-rates problems by writing the geometric constraint first and then differentiating both sides with respect to time, stating the chain-rule step.

  • Count outcomes with permutations, combinations and complementary counting, deciding explicitly whether order matters before choosing a formula.

  • Compute conditional probabilities, test for independence, and calculate the expected value of a random variable from its distribution table.

  • Handle 'exactly k' and 'at least one' probability questions using binomial reasoning and the complement rule.

Your checkpoint

A 45-minute, 8-problem probability set scored ≥80%, plus one related-rates problem solved with a labelled diagram and every differentiation step shown.

Week 7

Complex numbers and the complex plane (polar form, loci, De Moivre, equations) & Polynomials, equations and integer properties (factor theorem, rational roots, divisibility, Euclidean algorithm, base representations)

  • Convert complex numbers between rectangular, polar and exponential forms, and multiply and divide them using modulus and argument.

  • Apply De Moivre's theorem to compute powers and to list all n-th roots of a complex number, placing each root correctly in the complex plane.

  • Translate equations and inequalities into loci (circle, perpendicular bisector, half-plane, ray) and sketch the resulting region.

  • Factor polynomials with the factor theorem, locate rational roots, and solve higher-degree equations whose remaining roots are complex.

  • Run the Euclidean algorithm to find a gcd and to solve a linear Diophantine equation, and convert integers between base 10 and another base in both directions.

Your checkpoint

A hand-drawn complex-plane diagram showing all n-th roots of one chosen number with their arguments labelled, plus 10 polynomial-and-integer problems scored ≥85%.

Week 8

Plane and solid geometry (triangles, circles, congruence/similarity, inscribed solids, coordinate geometry) & Differentiation and its applications (limits, derivatives, tangents, maxima/minima, curve sketching)

  • Apply congruence and similarity to prove length and angle relations in triangles and circles, including cyclic quadrilaterals and the power of a point.

  • Compute lengths, areas and volumes for solids inscribed in or circumscribed about other solids by working through a cross-section.

  • Use coordinate geometry to derive circle equations, impose tangency conditions, and compute the distance from a point to a line.

  • Complete two full mock papers under timed conditions and classify every lost mark by domain to build a final revision list.

Your checkpoint

Two timed mock papers, fully marked, with a ranked list of your three weakest topics and a one-page remediation sheet for each.

Milestones

Week 2: Write the product, quotient and chain rules from memory, then solve one 15-minute curve-sketch problem using only a sign chart, scoring ≥75%.

Week 4: Solve one exam-style problem from each of Domains 1, 2 and 3 back-to-back in 45 minutes with no notes, scoring ≥70%; record which step broke down if you fall short.

Week 6: Complete one vector problem and one probability problem in 30 minutes without the formula sheet, scoring ≥70%, and confirm you can state the dot-product angle formula and the expected-value definition unprompted.

Week 8: Score ≥60% overall on a full 90-minute mock with no domain below 40%; if any domain falls below, work the matching remediation sheet before the exam.
