👉 Learn how to evaluate the six trigonometric functions of a given angle. When given an angle we locate the angle on the unit circle. Then using the coordinate of the terminal side of the angle on the unit circle and the definitions of...

👉 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...

Politeness Theory and Face (Goffman and Brown & Levinson) can help us have difficult conversations and communication effectively. This video gives examples of how positive and negative politeness sound in a conversation.

Politeness...

Learn the basics of vector operations. Vectors can be added, subtracted and multiplied. To add or subtract two or more vectors, we add each of the corresponding components of the vectors. To multiply a scalar to a vector, we simply...

👉 Learn how to evaluate the limit of a function involving rational expressions. The limit of a function as the input variable of the function tends to a number/value is the number/value which the function approaches at that time. The...

As always, the steps of DNA electrophoresis depend on your specific lab and protocol. Here, we look at the general theory of separating DNA on an agarose gel by electrophoresis and what it is used for in the lab. We will also learn about...

For method of sections: 1) Draw a free body diagram of the entire structure. 2) Choose your section wisely (make sure the variables you want are part of section you've chosen). 3) Solve using static equilibrium equations (sum of forces =...

This video covers a purely geometric way to understand both Fourier and Laplace transforms (without worrying about imaginary numbers). <b<br/>r/>

In this video, the teacher explains how to graph equations using a table of values. They demonstrate the process using two examples: X + y = 7 and X^2 + y^2 = 25. By choosing values for X or Y and solving for the other variable, they...

👉 Learn how to apply transformations of a figure and on a plane. We will do this by sliding the figure based on the transformation vector or directions of translations. When performing a translation we are sliding a given figure up,...

👉 Learn how to graph quadratics in standard form. A quadratic equation is an equation whose highest exponent in the variable(s) is 2. To graph a quadratic equation, we make use of a table of values and the fact that the graph of a...

Understand how to add integers using color counters. By combining the counters and canceling out zero pairs, students can easily visualize and solve addition problems involving integers. The teacher emphasizes the importance of neatness...

In this video, the teacher explains the concept of positive and negative numbers by comparing their distance and direction from zero. The teacher uses number lines and real-life examples, such as money and temperature, to illustrate how...

This video lesson explains the rules for multiplying a positive integer by a negative integer using the distributive property. It emphasizes the importance of not overlooking the second number when using the distributive property and...

👉 Learn how to find all the zeros of a polynomial given one rational zero. A polynomial is an expression of the form ax^n + bx^(n-1) + . . . + k, where a, b, and k are constants and the exponents are positive integers. The zeros of a...

Learn how to solve the particular solution of differential equations. A differential equation is an equation that relates a function with its derivatives. The solution to a differential equation involves two parts: the general solution...
