Explore how position and displacement vectors describe motion in two and three dimensions using i, j, k notation. Learn how to calculate vector differences and understand reference frames in kinematics

Learn how the area under a velocity-time graph gives displacement or distance, depending on direction. We'll break it down using shapes (triangles, trapeziums), signed areas, and integration principles for non-linear motion.

Learn how gravitational force does positive or negative work to transform an object's kinetic energy during ascent and descent. This Class 11 Physics lesson explains the work-energy theorem through real-life vertical motion scenarios.

Delve into instantaneous acceleration, the rate at which velocity changes at an instant. Learn to derive it from velocity-time graphs and understand how it differs from average acceleration.

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 explore the relationship between tangent segments and secant segments.

In this video, we write linear functions in point-slope and slope-intercept form given two points and one point and the slope.

In this video, we write equations of lines that are parallel and perpendicular to a given line.

In this video, we solve more exponential equations by rewriting the terms so that they have the same base.

In this video, we solve three questions (in order of ascending difficulty) where we solve exponential equations by using logarithms.

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 my second video over literal equations, we do problems that are slightly more challenging. We solve one problem for the variable that is in the denominator and solve two word problems.

How to use the Law of Sines to find sides and angles. In this video, we will see how to use the Law of Sines in two practice problems. We will first solve for a side length in a triangle, then we will solve for an angle.

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...

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

This video explains how to use the quadratic formula to solve quadratic equations

In this video, we derive the rule for writing geometric sequences using the "n-1" notation.

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 A2B - write linear equations in two...

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: A3C - graph linear functions on the...

In this video, we discuss how to solve literal equations that are more difficult, these examples require that you FACTOR to isolate the variable in question.

This video examines the basics of how to solve linear equations, and tell if your equation has one, zero, or infinite solutions.

In this video, we write equations in slope intercept form by starting with point-slope form.
