This organic chemistry video tutorial explains the difference between stereoisomers and constitutional isomers. It also shows you how to identify meso compounds, enantiomers, diastereomers, and cis trans geometric isomers. In addition, it discusess chirality - that is, it explains how to determine if a molecule is chiral or achiral due to the presence of an internal plane of symmetry. This stereochemistry based video contains plenty of examples and practice problems.

When working with a normal distribution you are provided a mean and standard deviation. The empirical rule tells us that there is 68%, 95%, and 99.7% of the normal distribution contained in the first, second, and third standard deviation away from the mean, respectively.
Where do these numbers come from?
In this video, an overview about integrals and the relationship to the standard distribution probability density function provide insight into where these numbers come from.
Some images made using Geogebra.

1:05 Normal Distribution probability density function.

3:11 Integrals to compute area between standard deviation of the mean for N(0,1) example.
4:29 Setting up table to compare areas for different normal curves.
5:01 How does changing the standard deviation change the spread of the curve?
5:40 Integrals to compute area between standard deviation of the mean for N(0,0.5) example.
6:35 Integrals to compute area between standard deviation of the mean for N(50,10) example.
7:30 Integrals to compute area between standard deviation of the mean for N(1000,25) example.
7:45 Conversation about how area under curve didn't change when varying the mean and standard deviation.
8:12 The empirical rule saves you time from recalculating integrals over and over again.

Converting a standard form quadratic function to a graph can be accomplished by finding the y-intercept, vertex, and x-intercepts (if they exist) and fitting a parabola to those points. It is easy to find these points when a quadratic function is in Standard Form because they can all be found by plugging a, b, and c into particular formulas.
y-intercept: (0,f(0))
vertex: (-b/2a,f(-b/2a))
x-intercepts: use quadratic formula

Polynomial division (long division/ algebraic division) is similar to the long division process for two numbers. A small review of the long division format occurs at the beginning followed by two examples (one where the remainder is zero and another where the remainder is non-zero).
These examples were selected to motivate the connection between factoring polynomials of degree greater than two to the polynomial division process.

U substitution (Integration by Substitution) is a common approach to solving integrals that contain a composition of functions. A function is contained within another function with its derivative nearby. These type of problems could be solved using U-Substitution.

The process of completing the square for a quadratic expression, equation or, function can be hard to complete. Depending on the instructions you may have to also graph the function once it is in vertex form, or find the x-intercepts using vertex form.
This video goes through three examples with various levels of difficulty.

Anytime you have an expression that contains multiple variables raised to powers and you are told to simplify the expression completely, you need to be aware of all the rules for exponents.
When dividing variables that contain a common base we use the following rule to simplify:
x^m/x^n=x^(m-n)

Indefinite and definite integral problems begin the same way but differ in how you interpret their results.
The result of an indefinite integral is a family of functions whereas a definite integral determines the area underneath the function you are integrating over the closed interval [a,b].

Z-scores are used to relate any normal distribution to the standard normal distribution (mean =0, standard deviation =1). Once you have a z-score, you have to use a z-score table in order to calculate probabilities or areas underneath the standard normal curve.
This video focuses on how to use a z-score table to answer simple questions about z-scores and the percent of the distribution contained below, above, or between given z-scores.
