Understand why roads are banked and how they enable safe circular motion without relying on friction. This lesson covers key derivations, formulas, and real-world applications for Physics students

This video discusses how to solve distance rate time word problems with systems of equations. You will often see these types of problems dealing with two different trains, or two different airplanes, traveling in the same or different...

In this video, we use substitution to take equations and rewrite them in the form of a quadratic so that we can solve them.

In this video, we solve equations with radicals. In the first example, we solve an equation with a single radical. In the second problem, we solve an equation with two radicals.

In this video, we examine how to solve absolute value equations. We try to develop a conceptual understanding by representing the equations on a number line.

In this video, we look at two examples of absolute value equations. The first is a quadratic absolute value equation. The second is an absolute value equation with no solutions.

Find all six trig ratios given a point on the terminal side of theta. In this video we work this common type of problem. We use the Pythagorean Theorem to find "r" (hypotenuse), and then use the given "x" (adjacent) and "y" (opposite) to...

In this video we solve two systems of nonlinear equations. The first has an absolute value function and a circle (and we solve by graphing). The second has a linear function and a quadratic.

A literal equation is an equation with more than one variable. These problems will sometimes have you solve for a variable, so that your solution is in terms of other variables. This will happen very often in formulas for science.

How do you solve equations with radicals? How do you solve equations with more than one radical, or with radicals on both sides? This video includes two examples of how to solve this type of problem.

How do you write parametric equations when given a table? This video shows how you can use a given table of values to write parametric equations.

How do you type parametric equations into the calculator? In this video, we answer this question by showing step by step instructions (including all the settings) of how to type this kind of relationship into the calculator.

How do you eliminate the parameter in parametric equations? How do you eliminate the parameter with sin and cos? This video works through three examples of rewriting parametric equations in standard rectangular form.

How do you convert equations between rectangular and polar forms? This video covers a variety of problems step-by-step by using some properties of polar functions.

Learn how to use parametric equations to solve projectile motion problems in this informative and engaging video. We’ll explore the concepts of initial speed, angle of projection, and height above the horizontal to model the path of a...

Watch this video to find out the basics of writing an equation in point slope form!

How to write an equation in slope intercept form when given.... 1) a point and the slope 2) two points

This is the second of two videos on solving systems of equations using the substitution method.

This is the first of two videos on solving systems by elimination or combination. Be sure to look for my second video on this topic (coming soon).

This video explains how to solve polynomials equations by factoring and using the zero product property

In this video you will learn how to solve equations with variables on both sides, such as 3x + 3 = x + 7

In this video, you will learn how to solve equations that have decimals by eliminating the decimals first. You will accomplish this by multiplying each side of the equation by the a power of ten (10, 100, 1000, etc).

How to solve word problems using point-slope form of a line. Typically, students are very comfortable using slope-intercept form of an equation, but we rarely see examples where using point-slope form is the most efficient. In this...

Algebra 1 STAAR/EOC released test questions. These are practice problems meant to help you review and practice as you prepare for your STAAR test / EOC test for Algebra 1 (Texas). Readiness standard A5A: solve linear equations in one...
