    Study Notes

    Analytical Geometry

    • Slope of AC is infinity, and slope of PD is 0.
    • Point D is (2, 2), and point C is (-3, -1).
    • Equation of AP is x + 2y = 3, and equation of BC is 3x - y + 8 = 0.

    Algebra

    • The number of real solutions of the equation e^4x + 4e^3x - 58e^2x + 4ex + 1 = 0 is 2.
    • Equation 25sin^4α + 10(1 - sin^2α) = 6 is equivalent to 25sin^2α - 10sin^2α - 10sin^2α + 4 = 0.
    • The equation 2^15sin4α + 10(1 - sin^2α) = 6 has solution sin^2α = 4/5.

    Inequalities

    • Let S1 = {x ∈ R - {1, 2} : (x + 2)(x^2 + 3x + 5) ≥ 0}, and S2 = {x ∈ R : 32x - 3x + 1 - 3x + 2 + 27 ≤ 0}.
    • S1 ∪ S2 is equal to (-∞, -2] ∪ [1, 2].

    Matrices

    • If PQ = kI, then P is an invertible matrix, and Q = kP^(-1).
    • adj(P) = k, and Q = kP^(-1)I.

    Complex Numbers

    • If α is a 7th root of unity, then 1 + α + α^2 + ... + α^6 = 0.
    • The equation x^2 + x + 2 = 0 has solutions p and q, where p = α + α^2 + α^3, and q = α^4 + α^5 + α^6.
