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
Numbers Can be Positive or Negative – Negative sign + Positive sign No Sign Means Positive If a number has no sign it usually means that it is a positive number. Any numbers greater than zero are described as positive numbers. Usually, we don’t put a plus sign in front of positive numbers because the
Irrational means not Rational An Irrational Number is a real number that cannot be written as a simple fraction. Example Rational Number 0.5 = ½ Irrational Number √2 = 1.414213562373095… = ?/? Rational Numbers A Rational Number can be written as a Ratio of 2 integers (ie a simple fraction). Irrational Numbers The numbers that
Sequence A Sequence is a set of things (usually numbers) that are in order. 2, 4, 6, 8, … Geometric Sequences In a Geometric Sequence, each term is found by multiplying the previous term by a constant. This sequence has a factor of 3 between each number. Each term (except the first term) is found
Matrix not only has addition and subtraction but also it has multiplication. There are some rules of multiplication of matrix depend on the problem. Matrix has some type of multiplication problem: Multiplication with a constant (Scalar Multiplication) Multiplication of matrix with a constant has simple concept. It is just multiplying each element of matrix with
Definition of Parallel Lines If 2 lines are parallel, their slopes are same. Slope is the value m in the equation of a line. y = mx + b If two lines are parallel lines, they will never intersect. They have exactly the same steepness which means their slopes are identical. Since: Slope is a
Right Triangle The Trigonometric Identities are equations that are true for Right Angled Triangles. Each side of a right triangle has a name: Adjacent is always next to the angle Opposite is opposite the angle Sine, Cosine and Tangent 3 main functions in trigonometry are Sine, Cosine and Tangent. They are just the length of one
What is a Denominator? The denominator is the bottom number in a fraction. It shows how many equal parts the item is divided into Common Denominator? When the denominators of 2 or more fractions are the same, they have Common Denominators. Finding a Common Denominator One simple answer is to multiply the current denominators together.
Definition of Quartiles What are Quartiles? In statistics, Quartiles are values that divide your data into quarters. They aren’t shaped like pizza slices. Quartiles divide your data into 4 segments according to where the numbers fall on the number line. The 4 quarters that divide a data set into quartiles are: Lowest 25% of numbers. Next lowest
