    Study Notes

    Conic Sections

    • Conic sections are formed by the intersection of a plane with a double cone
    • Circle: The plane is parallel to the base of the cone
    • Ellipse: The plane is tilted at an angle
    • Parabola: The plane is tilted further and becomes parallel to the cone's surface
    • Hyperbola: The plane is tilted even further so that it intersects both cones

    Circle

    • A circle is the set of all points on a plane that are equidistant from a fixed point called the center.
    • The distance from any point on the circle to the center is called the radius.

    Parabola

    • A parabola is the set of all points on a plane equidistant from a fixed point called the focus and a fixed line called the directrix.

    Ellipse

    • An ellipse is the collection of all points in a plane such that the sum of the distances of each point from two fixed points in the plane is constant.
    • These fixed points are called foci.

    Hyperbola

    • A hyperbola is the set of points in a plane such that the difference in distances of each from two fixed points in the plane is constant.
    • The difference is not necessarily positive, but it is fixed for any point on the hyperbola.

    Systems of Nonlinear Equations

    • Systems of nonlinear equations involve two or more equations with at least one equation that is not linear.
    • A linear equation forms a straight line on a graph and has a maximum degree of 1.
    • A nonlinear equation forms a curve on a graph and has a maximum degree of 2 or more.

    Sequence, Series, and Sigma Notation

    • A sequence is a list of numbers in a particular order, where each number is obtained according to a specific rule.
    • A series represents the sum of the terms in the sequence.
    • Sigma notation (summation notation) is used to denote a sum.

    Mathematical Induction

    • Mathematical induction is a technique used to prove statements or formulas for all natural numbers.
    • Steps:
      • Verification: The statement is verified for n = 1.
      • Induction Hypothesis: Assume that the statement is true for n = k.
      • Prove: Prove that the statement is true for n = k + 1.
      • Conclusion: The statement is true for n = 1 and it's true for n = k + 1 if it's true for n = k, therefore it's true for any natural number (n).

    Binomial Theorem

    • A binomial is an expression with two terms.
    • Binomial expansion involves expanding an expression in the form (a + b)^n, where n is a positive integer.
    • The binomial theorem helps expand binomials raised to specific powers.

    Pascal's Triangle

    • Pascal's triangle is closely related to the binomial theorem.
    • The first row consists of 1. Each row after the first consists of one more term than the previous row.
    • Each row after the first begins and ends with 1.
    • Every value, other than the first and last, is obtained by adding the pair of numbers immediately above it.
    • The numbers in each row are symmetric about the center.

    Properties of the Binomial Theorem

    • The exponent of a starts at n, decreases by 1 each time, and reaches 0 in the last term.
    • The exponent of b starts at 0, increases by 1 each time, and reaches n in the last term.
    • The coefficients of the terms are the numbers in Pascal's Triangle that correspond to n.

    Finding the nth Term

    • The formula to find the nth term is the same as the binomial theorem but without the sigma.
