Study Tips
- 1
Know the quadratic formula cold: x = (−b ± √(b²−4ac)) / 2a. Learn to identify when to factor vs. when to use the formula.
- 2
Logarithm rules (product, quotient, power) must become automatic before the final exam — they underpin all log/exponential problems.
- 3
For sequences: know the formulas for arithmetic (aₙ = a₁ + (n−1)d) and geometric (aₙ = a₁rⁿ⁻¹) and their sum formulas.
- 4
Complex numbers (a + bi): remember i² = −1 and use FOIL for multiplication. Rationalize denominators by multiplying by the conjugate.
Past Exam Questions
Solve for x: log₂(x + 3) + log₂(x − 3) = 4. Check for extraneous solutions.
Common Mistakes to Avoid
- ✕
Memorizing procedures without understanding when to use them — exams disguise familiar problems in new contexts.
- ✕
Skipping steps in working, which throws away method marks when the final answer is wrong.
- ✕
Not sanity-checking answers for reasonableness (wrong units, impossible magnitudes, extraneous solutions).
