Definition of Infinite Series Infinite series are the sum of infinitely many numbers listed in a given order & related in a given way. For an infinite series a1 + a2 + a3 + … , a quantity sn = a1 + a2 + … + an, which involves adding only the first n terms, is called a partial sum. For Sn approaches a fixed number
Have you ever eaten ice cream? One of the shapes is cone. Besides that, other cone things are traffic cone, cone snail, party hat, megaphone, etc.. Definition of Cone Cone is a three-dimensional shape that has a flat base, a curved surface, and a point in the top (apex). The flat base is circular shape
Definition of Additive Inverse The additive inverse of a number is another number you add to a number to create the sum of zero. In other words, additive inverse of x is another number, for examle y, as long as the sum of x + y equals zero. The additive inverse of x is equal
Circle is one of familiar shape in daily life. It was studied since long time ago. There are many things that is circle such as clock, wheel, gear, ring, coins, etc.. Definition of Circle Circle is two-dimensional shape. It is set of points that has same distane from the center in a plane. In another words, there are
Composite number is a whole number that can be made by multiplying other whole numbers. Example: 10 can be made by 5 × 2 so is a composite number. Not Composite number 5 = 1 × 5, Is not composite number because 1 × 5 isn’t using other whole numbers 7 = 2 × 3.5, Is
Equivalent Fractions have the same value, even though they may look different. These fractions are really the same: Why are they the same? Because when you multiply or divide both the top and bottom by the same number, the fraction keeps it’s value. The rule to remember is: “Change the bottom using multiply or divide,
Invers of a matrix relate with identity of a matrix. It is symbolized by “X-1” where “X” is a matrix X. if there is matrix A, then the invers is A-1. The result of multiplication between matrix A and A-1 is identity matrix “I”. In mathematics symbol, it is written as A.A-1 = I or A-1.A =
A Differential Equation is an equation with a function and one or more of its derivatives: Example: an equation with the function y and its derivative Homogeneous Differential Equations A first order Differential Equation is Homogeneous when it can be in this form: We can solve it using Separation of Variables but first we create
Determinant of a matrix is a scalar value. It is calculated from square matrix. Its means that only matrix that has dimension 2×2, 3×3, 4×4, etc. Determinant of matrix is used to solve some problem in mathematics. They are like system of linear equation, calculus problem, and especially invers matrix. If there is matrix A,
There are 3 Simple Steps to Divide Fractions: Turn the second fraction (the one you want to divide by) upside down (this is now a reciprocal). Multiply the first fraction by that reciprocal of second fraction Simplify the fraction (if needed) Fractions and Whole Numbers What about division with fractions and whole numbers? Make the
