WEBSITE: http://www.teachertube.com This video demonstrates the use of the Conics application on the TI83 and TI84 series of graphing calculators. Circles ellipses and hyperbolas are evaluated. There is a discussion of changes in h and k shifting the location of the conic. Standard forms of equations are explained. There is also some time taken to show basic the basic algebra of solving for y in order to graph. For ellipses major and minor axes are defined.
WEBSITE: http://www.teachertube.com This video demonstrates changing logrithmic equations into exponential equations and changing exponential equations into logarithmic equations. Exponential and logarithmic equations are different forms of the same principle. The video points out the advantage of being able to do this depending on what the unknown isif the unknown in an exponential equation is the exponent for a given base that exponent can be isolated and solved for by converting it to a logarithmic equation. Conversely if in a logarithmic equation like logx 4 we can solve for x more easily be changing it into 10 to the power of 4 x. Whatever isolates the unknown is what you need to use.
