Bridges. Bridges don't deal well with temperature changes. In order to combat this, engineers have come up with some work arounds that allow bridges to flex as they expand or contract. In this episode of Crash Course Physics, Shini talks...

In this video Paul Andersen explains how stoichiometry can be used to quantify differences in chemical reactions. The coefficients in a balanced chemical equation express the mole proportions in that reaction. These values can be used...

New ReviewIn this video, I will show you how to graph trigonometric functions, specifically focusing on cosecant (csc) and sine. We will examine how to identify key characteristics such as amplitude and period to effectively graph these functions....

New ReviewWhen you are trying to solve a system of equations there are three tips that I want for you to remember.

In this math video lesson we will learn how to identify when an algebraic expression is in simplest form, how to simplify expressions by combining like terms, and how to use the distributive property to expand and simplify. Students...

A video entitled "Different Bases" that covers rewriting expressions using the rule for applying powers to expressions with different bases.

A video entitled "Coefficient" that covers the concepts involved in solving equations where the variable has a coefficient.

A video entitled "Add and Subtract Expressions" which shows how before adding and subtracting expressions it's important to understand written and unwritten coefficients.

Pupil outcome: I can represent problems with two unknowns and solve using an efficient strategy. Key learning points: - The model can represent a scaling structure with one part being __ times the size of the other. - The model can...

Pupil outcome: I can use the laws of indices to divide two powers where the bases are the same. Key learning points: - When dividing two terms, you can sometimes write this more simply. - If the powers have the same base, then the powers...

Pupil outcome: I can use the laws of indices to simplify a power raised to another power. Key learning points: - The index tells you how many identical terms you must multiply together. - By studying the structure of multiplication, you...

Pupil outcome: I can use the laws of indices to multiply two powers where the bases are the same. Key learning points: - When multiplying two terms, you can sometimes write this more simply. - If the powers have the same base, then the...

Pupil outcome: I can write equations involving ratios. Key learning points: - Ratios can be written as fractions. - A ratio can be used to write an equation. - This equation is another way of representing how the two quantities are...

Pupil outcome: I can appreciate that writing linear equations in the form y = mx + c helps to reveal the structure. Key learning points: - Linear relationships can be written in a variety of algebraic forms. - It is possible to identify...

Pupil outcome: I can correctly identify: term, coefficient, factor, product, expression, formula, identity and equation. Key learning points: - Words you have used to describe numbers can also be used in algebra like factor and product....

Master the concepts of static and kinetic friction in this ultimate Class 11 Physics guide. Learn the causes of friction, key formulas, and how to calculate coefficients of friction with real-world examples

In this video we learn how to solve systems of equations with elimination / combination.

How to do partial fractions with repeated linear factors? If you have something squared or cubed in the denominator, how does that change your setup for partial fractions problems? In this video we examine how a different problem will...

In this video, we discuss how to multiply terms that have radicals.
