    Verifying Trigonometric Identities 2

    In this episode, there are 2 examples of verifying trig identities that I would rate on the more difficult side.  More advanced strategies are needed such as factoring and finding a common denominator.  While that sounds easy, it is often difficult to see when verifying trig identities.

    Verifying Trigonometric Identities

    In this episode, we look at verifying trig identities.  There are 3 examples that I would rate on the easier side.  You need to start somewhere.

    What is a Podcast?

    This podcast is not about math.  This is just a simple explanation of what a podcast is.  I have created this podcast to help my students learn more about podcasts.  They will eventually help me make more math podcasts.  I am very much so looking forward to this project.

    Solve a quadratic equation by using substitution 2

    Here is another example how to use substitution to solve a quadratic equation.  Now I know that there are other ways to solve this particular example (squaring both sides), but I wanted to show that substitution is a good way to solve a quadratic equation.

    Solve a quadratic equation by using substitution

    Sometimes we will encounter a problem that just looks ugly.  In other words, it is one of those problems we just would rather skip.  However, as you will see in this problem, substituting a quantity for a single variable really does make the problem much more manageable.

    Graphing a quadratic in vertex form 2

    Here is another example of graphing a quadratic equation that is in vertex form.  In this example, a is negative which causes the graph to open down and frown:-(

    Graphing a quadratic in vertex form

    Graphing a quadratic equation is not a difficult task.  Here are the main things to find:  the vertex, the axis of symmetry, the y-intercept, and the x-intercepts.  Use the fact that a parabola is symmetrical also makes it easier for us to find additional points.
