" Fuente: BrightStorm"Solving "Greater Than" Absolute Value Inequalities" es un video-tutorial (en inglés) de ©Brightstorm , en su portal disponen de muchos otros vídeos gratuitos de ciencias (Matemát ...
"When given a trinomial, or a quadratic, it can be useful for purposes of canceling and simplifying to factor it. Factoring trinomials is easiest when the leading coefficient (the coefficient on the s ...
"In a polygon, an exterior angle is formed by a side and an extension of an adjacent side. Exterior angles of a polygon have several unique properties. The sum of exterior angles in a polygon is alwa ...
"Slope-intercept form of a line is a general formula for the equation of a line. Using the slope-intercept form of a line helps in finding the slope of a line from an equation and the intercept direc ...

"One of the most important things to understand about lines is the slope. Slope is the 'steepness' of the line, also commonly known as rise over run. We can calculate slope by dividing the change in t ...
"Sometimes we use methods for expanding logarithms in complicated logarithmic terms. Expanding logarithms can be useful for obtaining more simplified terms. When expanding logarithms we use the rules ...
"When evaluating the tangent function, to find values of the tangent function at different angles, we first identify the reference angle formed by the terminal side and the x-axis. Then, we find the t ...
"Rational exponents indicate two properties: the numerator is the base's power and the denominator is the power of the root. When evaluating rational exponents it is often helpful to break apart the e ...
"When we evaluate limits that are not continuous, we can use algebra to eliminate the zero from the denominator and then evaluate the limit using substitution. When evaluating limits algebraically we ...
