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.
