Rationalize the Denominator

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

Monomial: Definition, Degree, Operations, And Examples

Definition of Monomial Monomial is one of algebra form that consists of one term. It is also defined as mathematical expression that consists of one term. The term is a number or the result of multiply between coefficient and the variables. Variable is symbol to replace unknown number yet. The general form is Difference between

Inequalities: Definition, How to Solve, Linear, Quadratic, Examples

Definition of Inequalities Inequalities is different with equality clearly. Equality use equal sign (=) but inequality use inequal sign (≠, >, <, ≤, ≥). Look at the table to understand about the inequality signs. Sign Meaning Example ≠ Not equals with … 1 ≠ 2 ≥ Greater than or equal to … a2+1 ≥ 10for

Algebra

Algebra (“al-jabr”, from Arabic) literally meaning “reunion of broken parts”. Algebra is one of the broad parts of mathematics, together with number theory, geometry and analysis. In its most general form, algebra is the study of mathematical symbols and the rules for manipulating these symbols. It includes everything from elementary equation solving to the study

Even & Odd function

Every function has each graph, but not all of the graph symmetric to x-axis, y-axis, or others. If the graph has symmetric, it concludes to specific case that the function is even or odd function. Even function and graph Even function is different mean with even numbers. The graph of even function is symmetric to

Pythagoras Theorem

When a triangle has a right angle (90°) and squares are made on each of the 3 sides, then the biggest square has the exact same area as the other 2 squares put together! Pythagoras Theorem can be written in one short equation: a2 + b2 = c2 Where: c is the longest side of the triangle

How to Find Intercepts From an Equation

x Intercept is where the graph of an equation crosses the x-axis y Intercept is where the graph of an equation crosses the y-axis How To find the intercepts What Intercept Steps x intercepts (x, 0) 1. Set y=02. Solve for x y intercepts (0, y) 1. Set x=02. Solve for y Learn More General

Simplifying Square Roots

To simplify a square root, make the number inside the square root as small as possible. How to Simplifying Square Roots Rule   where a, b > 0 Simplifying Square Roots for Fractions Rule Surds Surd is a root we can’t simplify further. So √5 is a surd. But √9 = 3 is not a surd. Learn

Law of Sines & Cosines: Formula & Examples

Solving trigonometry’s problem that use right angle can be done by using right triangle and Pythagorean theorem. But, in other problems it does not use right triangle. It uses any triangles. The solution is using law of sines and cosines. It will be more complex than using right triangle but it does not mean difficult.
