Professor Richard Evans recalls that the teacher who most influenced him was John Walsh, a history tutor at Jesus College, Oxford, where Evans studied in the 1960s. Walsh was known for prioritizing teaching over publishing and was deeply...

Now that we know how to classify differential equations, we have to learn how to solve them. Let's start with the easiest ones to solve, separable first-order differential equations. This will involve some simple algebra and then basic...

We just got our feet wet with separable differential equations, so now let's look at something slightly trickier. Solving linear first-order differential equations will require a little bit more effort, involving something called an...

To determine the area of a triangle, you use the formula: Area = 1/2 × Base × Height. This formula works because a triangle is essentially half of a rectangle or square. By identifying the base (the bottom side) and the height (the...

To determine the perimeter of a triangle, you simply add the lengths of its three sides. Whether it’s a scalene triangle with different side lengths, an isosceles triangle with two equal sides, or an equilateral triangle where all sides...

Triangles can also be classified based on their angles. An acute triangle has all three angles less than 90 degrees, a right triangle has one angle exactly 90 degrees, and an obtuse triangle has one angle greater than 90 degrees. No...

Triangles have unique properties that define their shape, sides, and angles. They can be categorized based on their sides: scalene (all sides different), isosceles (two sides equal), and equilateral (all sides equal). Throughout history,...

The War of 1812, between the United States and Great Britain, ended with the Treaty of Ghent. This historic agreement, negotiated in Belgium over five months, proved that the U.S. could achieve its aims through diplomacy.

Landforms are natural features on Earth's surface. They come in all shapes and sizes. In this video, learn about the different landforms found in the United States.

Discover Earth's physical features, from oceans to mountains, and learn how land and water form our planet's diverse landscapes.

Why do we flip the inequality sign when multiplying or dividing by a negative number? 🤔 In this video, Math Defined with Mrs. C explains the concept with a step-by-step example: -x + 10 is less than 4. Watch as she demonstrates two...
