Key ideas

  1. An arithmetic sequence adds a constant common difference d each step.

  2. A geometric sequence multiplies by a constant common ratio r each step.

  3. The factor theorem: (x − a) is a factor when P(a) = 0.

  4. Where f(x) = 0, the reciprocal y = 1/f(x) has a vertical asymptote.

  5. (f ± g)(x) = f(x) ± g(x), combined pointwise.

Watch out for

  • Using n instead of (n − 1) in the general term.
  • Using a common difference instead of a ratio.
  • Testing candidates that do not divide the constant term.

PCB4
Expand powers of a binomial in a variety of ways, including using the binomial theorem

Key ideas

  1. If one step has m outcomes and the next has n, together they have m·n outcomes.

  2. A combination is an unordered selection; ₙCᵣ = n!/(r!(n − r)!).

  3. The principle extends to any number of independent steps.

  4. Order does not matter — {A, B, C} is one combination.

  5. Restrictions (no repeats, a fixed first choice) change the count at each step.

Watch out for

  • Adding the choices instead of multiplying them.
  • Using a permutation when order does not matter.
  • Ignoring a no-repeats restriction that reduces later choices.

L4
Explore limits which involve infinity
L4
Explore limits which involve infinity

Key ideas

  1. lim(x→a) f(x) is the value the graph approaches near x = a.

  2. A function is continuous at a if f(a) exists, the limit exists, and they are equal.

  3. The limit can exist even where the function is undefined or has a hole.

  4. A removable discontinuity is a hole; a jump has unequal one-sided limits.

  5. The limit describes approach, not the value f(a) itself.

Watch out for

  • Reporting f(a) instead of the value approached.
  • Calling a function continuous where the limit and f(a) differ.
  • Assuming a limit fails to exist just because there is a hole.
