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...

This is the first of two videos on solving systems of equations using the substitution method. Make sure to watch "Solving Systems by Substitution 2" for help with solving systems when both equations are in standard form!

In this video, we will dilate figures on the coordinate plane when the center of dilation is not the origin. The first example is a standard dilation (enlargement) with a non-origin center, and the second example gives you both the...

This video explains how to graph linear two-variable inequalities. It covers identifying solution and non-solution points, plotting the boundary line, choosing the correct shading, and understanding when to use dotted versus solid lines....

Humans have been drinking alcohol for thousands of years, starting with apes that ate fermented fruit. Early societies used alcohol not just for fun, but also for nutrition, hydration, and even medicine. Over time, different cultures...

Making things like cement, steel, and chemicals uses a lot of energy and is one of the hardest parts of the economy to clean up. A big problem is that about half the energy is wasted as heat, but better factory design and using things...

Introduction to C Programming using DevC++

DNA polymerases are the enzymes that build DNA in cells. During DNA replication (copying), most DNA polymerases can “check their work” with each base that they add. This process is called proofreading. If the polymerase detects that a...

This video explains how the technique of flow cytometry is used to detect for the presence of apoptotic cells in a given cell population. The technique used is Annexin V-Propidium iodide staining. Annexin V is a calcium-dependent...

Polyacrylamide gel electrophoresis (PAGE) uses a gel matrix formed by polymerizing acrylamide and bis-acrylamide through free radicals generated by TEMED and APS. This exothermic polymerization forms linear chains cross-linked into a 3D...
