Parabolic Problems

By Altum Spectent

Another problem I have seen lately is that of parabolas and symmetry, as well as that of intervals, domains, ranges, and other graphical dilemmas. If one is asked to define the interval over which a function is increasing, decreasing, or remaining the same, the answer is always (x 1 , x 2 ). One never uses brackets when referring to an interval! However, if one is asked to define a domain or range, the answer could include one or more brackets: (x 1 , x 2 ], [x 1 , x 2 ), or [x 1 , x 2 ] if referring to the domain; (y 1 , y 2 ], [y 1 , y 2 ), or [y 1 , y 2 ] if referring to the range. (x 1 , x 2 ) and (y 1 , y 2 ) can also be used to describe the domain and range, respectively, in some cases. A function is said to be increasing if the y-values are getting larger, decreasing if they are getting smaller, and constant if they are remaining steady. The domain of the function is the entire group of all the x -values for which the function is continuous, while the range is the entire ...

Systems of Linear Equations

I'm back! Sorry for the tardiness, but college students never have much extra time on their hands. Anyway, today's post will be a mathematical review; coming directly from a recent tutoring session in which I helped a student with  systems of linear equations . Systems of linear equations can be solved by using either the substitution method, the addition method, or the graphical method. Sometimes more than one method is required, especially for systems of three equations, each with the same three variables. Personally, I prefer the addition and substitution methods, but the graphical method is fine, too. Say we are given the following system of linear equations: This is very simple and straightfor ward example. We can solve this easily using the addition method, which would simplify to 3x = 6 , which would further simplify to x = 2 . Using this result, we can solve for y : (2) - y  = 1  à  2 - 1 = y  à  y = 1 . Or 2(2) + y = 5  à ...

The Science of Speech

By Altum Spectent
Speech classes can be very frightening, for a myriad of reasons: The professor may seem overconfident in your skills as a speaker You may be introverted to a certain extent You may not feel ready for public speaking You may not feel that you have the right words And many more... However, you can overcome the situation! Often, simply having someone—such as your professor—believe in you can help you do so. To avoid feeling as though you have the wrong words, it does help to choose a topic with which you feel comfortable and also to know something about it. Then, you can draft a speech at home and practice several times, and also make note cards with reminders about what to talk about and when. One big aid is having a manuscript speech written out, with which you are familiar, and extemporize on that. Then, even if you become stuck for words, you will still have your manuscript to fall back on for guidance.
