This video gives us an quick revision on 'Circle' from our interesting series 'Some Stupid Math Mistakes'

Test your knowledge of The Circle of Fifths! Can you answer these questions? The Circle of Fifths tells you everything you need to know about major keys, minor keys, and key signatures. This music theory lesson presents a light-hearted...

Zach Star demonstrates a surprising topological proof - you can always cut three objects in half with a single plane

A blue sky and fluffy bright clouds are things that are seen around the world. The atmosphere presents a multitude of sights and phenomena using light, air, water droplets, ice crystals, and dust. Many of the phenomena give clues to...

Planetary orbits are elliptical because gravitational interaction over time changes the delicate balance of mass, velocity and distance from the star which otherwise keeps planetary orbit circular. For a very long time, from Ptolemy to...

👉 Learn how to find the point on the unit circle given the angle of the point. A unit circle is a circle whose radius is 1. Given an angle in radians, to find the coordinate of points on the unit circle made by the given angle with the...

This video lesson teaches students how to measure angles using fractions of a circle. It explains the concept of angles and right angles, and demonstrates how to use a sprinkler on a field to visualize and calculate angle measurements....

👉 Learn how to find the point on the unit circle given the angle of the point. A unit circle is a circle whose radius is 1. Given an angle in radians, to find the coordinate of points on the unit circle made by the given angle with the...

Learn how to solve problems with tangent line. A tangent line to a circle is a line that touches the circle at exactly one point. The tangent line to a circle makes a right angle with the radius of the circle at the point of its...

Now that we've built the circle, how do we use it? What all can we do with the Circle of Fifths?

In This Episode, Tyler Teaches Us About How to Insert Text, Shapes, and Lines in GOOGLE SLIDES

👉 Learn how to evaluate an expression with the composition of a function and a function inverse. Just like every other mathematical operation, when given a composition of a trigonometric function and an inverse trigonometric function,...

👉 Learn how to evaluate the secant of the sum or difference of two angles using the sum/difference formulas. To do this, we first use the Pythagoras theorem to obtain all the sides of the right triangle in the unit circle. Recall that...

The video provides a clear explanation of the sine, cosine, and tangent functions and their corresponding graphs. It starts by introducing the unit circle and how it relates to the functions. Then, it explains the formulas for each of...

This video quiz on the topics covered in the Circles series. The series covered key concepts related to circles, including the radius, diameter, circumference, and area. It also touches on finding the area and volume of...

In this video, the teacher explains how to represent a situation using inequalities. They use examples such as comparing unknown numbers to a given value or representing temperature ranges. The teacher demonstrates how to write the...

This video covers exam strategy, Geometry, Perimeter, Area, Angles, Circles. This is part 14 from the series 'Introduction to the Math Section of the SAT'.

👉 Learn all about evaluating trigonometric functions with triangles. In this playlist, we will learn how to evaluate, sine, cosine, tangent, cotangent, secant, and cosecant when given the sides of a triangle. If we have missing sides we...

👉 Learn how to find the extreme values of a function using the first derivative test. The extreme values of a function are the points/intervals where the graph is decreasing, increasing, or has an inflection point. A method that can be...

In this video, the teacher explains how writers use ellipses (...) to indicate pauses or breaks in dialogue. The lesson includes examples and guidelines for using ellipses correctly, as well as a practice activity for students to revise...

In this video, the teacher explains how to estimate the measure of angles using visual clues and benchmark angles. They give examples of estimating the angle of a plane's takeoff, the opening angle of a door, and the angle formed by bike...
