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 ...

Chemical Mixture Problems

By Altum Spectent
Recently, I tutored a few students in math, and they were having the same problem: How to solve a chemical mixture equation? Chemical mixture problems can pretty much always be solved with the equation: p 1 (v 1 ) + p 2 (v 2 ) = p 3 (v 1  + v 2 ) , where "p" refers to the various percentages of the chemical involved and "v" refers to the various volumes of the chemical involved. The question should give either all three percentages as well as one volume, or both volumes as well as two percentages. When solving a problem such as this, it is unimportant whether the percentage is listed as a number such as 75, or a decimal, such as 0.75, as long as the same method is used throughout the problem. Here is a sample question below: A chemist needs 150 milliliters of a 50% saline solution but has only 18% and 78% solutions available. Find how many milliliters of each that should be mixed to get the desired solution. So, we can start equating variables wit...

Essay Writing Tips

By Anonymous
When a professor assigns any type of paper, the first response for many is, "Oh, no! I can't do this! How many pages again?" This, however, is not the way to think, as this will lead students to feel overwhelmed—that the paper will be impossible to write. Instead, the thought should be, "What can I write about? What am I interested in?" Then, once a topic is chosen, one shouldn't look at the whole—look at the parts: the introduction, the body, the conclusion; the paragraphs, the sentences, the words. If a good sentence is written, with appropriate words, sentence structure, and tense, then the only thing to do is make sure the same tense is used throughout the paper, and that words, sentence structures, and sentence lengths are not overused. When this system is followed, it renders the writing process much easier, and less overwhelming. Once the paper is finished, the results can sometimes even surprise the author! To summarize: Look at the ...
