Trigonometric Ratios of Special Angles
By AlRichards314
This video shows us how we determine the trigonometric ratios for the angles of 30 degrees, 45 degrees, and 60 degrees. Keep in mind that the ratios of the sides corresponding to these angles never change (even though the side lengths may change). That means that knowing the values for these trig ratios means you'll know them forever! They won't change!

Newman Projections
By The Organic Chemistry Tutor
This organic chemistry video tutorial provides a basic introduction into newman projections. It explains how to draw the newman projections of ethane, butane, and 2,3-dimethylpentane. It explains how to draw the eclipsed and staggered conformations of ethane as well as the gauche and anti conformations of butane. It explains how to use conformational analysis to determine which conformation is most stable.
