In this video, the teacher explains how to identify extraneous solutions in radical equations. They emphasize the importance of avoiding negative numbers under a square root and explain that a negative radicand leads to an extraneous...

These second-order linear differential equations can be written in the form

dx/dt = ax +
by
dy/dt =
cx + dy
Depending on the values of a,b,c and d, the dynamics will be very different! They can be...

This video goes over the dot product also known as the scalar product. This video goes over 5 examples illustrating how to solve problems that make use of the geometric and component definition of the dot product.

In this video, the teacher explains the concept of Y equals MX and where it comes from. They use the idea of similar triangles to derive the equation. The lesson emphasizes that the equation represents a line passing through the origin...

In this lesson you will learn how to determine if a triangle is a right triangle by applying the Area of Squares Proof.

👉 Learn all about the quadratic formula. The quadratic formula is a formula which can be used to find the roots of (solve) a quadratic equation. The quadratic formula is given by x = (-b +/- sqrt(b^2 - 4ac)) / 2a, where a is the...

In this video, you will learn how to solve pairs of linear equations visually by using visual models. The teacher explains how drawings can help in solving equations and demonstrates this through examples.

Calculus based review of definite integrals, indefinite integrals, and derivatives as used in kinematics. Graphs of position, velocity, and acceleration as a function of time are compared using derivatives and integrals. Two of the...

👉 Learn how to find the value that makes a function continuos. A function is said to be continous if two conditions are met. They are: the limit of the function exist and that the value of the function at the point of continuity is...

👉 Learn how to find the points of inflection of a function given the equation or the graph of the function. The points of inflection of a function are the points where the graph of the function changes its concavity. The points of...

The video gives a brief overview of oxidation and reduction and then focuses on reactions at the cathode and anode in an electrolytic cell. The concept of half equations is introduced and demonstrated through examples, with a focus on...

The video is a lecture presentation demonstrating how to investigate the changes in resistance when resistors are added to a circuit in series and parallel. The presenter uses a circuit with a fixed resistor and measures the resistance...

👉 Learn how to find and write the equation of the tangent line of a curve at a given point. The tangent of a curve at a point is a line that touches the circumference of the curve at that point. To find the equation of the tangent line...

👉 Learn how to find the point of the horizontal tangent of a curve. A tangent to a curve is a line that touches a point in the outline of the curve. When given a curve described by the function y = f(x). The value of x for which the...

👉 Learn how to find and write the equation of the tangent line of a curve at a given point. The tangent of a curve at a point is a line that touches the circumference of the curve at that point. To find the equation of the tangent line...

👉 Learn how to solve two step linear equations. A linear equation is an equation whose highest exponent on its variable(s) is 1. To solve for a variable in a two step linear equation, we first isolate the variable by using inverse...
