Definition of Asymptote Asymptote is a line or curve that approach to another curve. It can be horizontal, vertical, or oblique asymptote. Asymptote is always approach to the curve but the distance is never zero. In another words, asymptote is never same as the curve. In mathematics, especially in analytic geometry, there are so many
Definition A Stem and Leaf Plot is a special table where each data value is split into a “stem” (the first digit or digits) and a “leaf” (usually the last digit). See this example: Example “47” is split into “4” (stem) and “7” (leaf). 10, 11, 22, 23, 24, 35, 36, 47, 48, 49 Stem
How move and resize the graphs of functions? How move the graphs of functions? Add a constant to the y-value will move it up or down Add a constant to the x-value will move it left or right Examples Function c > 0 c < 0 f(x) = x2 g(x) = x2 + c f(x)
Definition of Absolute Value Absolute value or modulus |x| of a real number x is the non-negative value of x without regard to its sign. |x| = x for a positive x, |x| = −x for a negative x (in which case −x is positive) |0| = 0. For example, the absolute value of 5 is
Definitions Conjugate is where we change the sign in the middle of two terms The conjugate of “a + b” is “a – b” Conjugate is only used in expressions with two terms (binomials) Examples Expressions Conjugate a + 1 a – 1 b2 – 2 b2 + 2 4 + √3 4 – √3 When we
Definition of Pyramid Pyramid is one of polyhedron form that connecting polygonal as the base and a point that called apex/vertex. As consequences there are base (polygonal that is like triangle, square, etc.) and some triangle sides as lateral sides. Type of Pyramid Depends on the Base Number of triangle depends on what type polygonal
Definitions There are 3 types of fractions Fraction type Condition Examples Proper Fraction Numerator < Denominator Improper Fraction Numerator > Denominator Mix Fraction A whole number + proper fraction So, An Improper Fraction is a fraction that has a top number larger than (or equal to) the bottom number. Converting Improper Fractions to Mixed Fractions How
Irrational Denominator Denominator: the bottom number of fraction Rational: Numbers such as 2, 3, 7 Irrational: Roots such as √2, √3, √7 Simplest form of number cannot have the irrational denominator. To be in simplest form, Rationalizing the Denominator! Rationalizing the Denominator is making the denominator rational How to Rationalizing the Denominator Rationalizing the Denominator
What is a Limit? Limit means value of a function that approaches another value. Limit is symbolized as It is read as “limit of function of x, as x approaches to a equal to L”. Look at the graph, Properties of Limits If there are two limits, Then Limits to Infinity limit to infinity is a
