So Many Functions, So Little Time…
Precalculus can be a challenging subject to understand even for the best math student. It follows in the footsteps of Algebra II to some extent but goes into more depth in dealing with various types of complex functions. For example, more emphasis is placed on looking at different characteristics of linear functions as well as the graphs of polynomial, absolute value, square root, radical, piecewise, exponential, logarithmic, conic, and trigonometric functions. These are analyzed while also focusing on understanding real-life word problems which incorporate many of these types of functions.
The Benefits of an Online Tutor
An online Precalculus tutor can help the student to fully comprehend the functions mentioned above. The tutor should utilize a full array of internet resources to compare and contrast the different functions. Another important aspect emphasized in Precalculus is the transformation of the graphs of functions. The online tutor can demonstrate the effect of a horizontal/vertical shift, stretch/compression, reflection, or rotation of any given function by using an online whiteboard and online materials. Many times, the student will decide that the online tutor is a better investment of time than an in-home tutor since the former can efficiently focus the entire tutoring session on teaching the principles needed to excel in Precalculus. The online tutor can keep the student engaged and focused on the material being presented by using a variety of tools and using the whiteboard to outline important points and concepts. The student also has the option of interacting with the online tutor on the whiteboard and printing any notes posted to the whiteboard.
The Benefits of a Homework Help Site
A homework help site can as well be of great use to a student needing clarification of a given topic or even a particular homework problem. A homework help site differs from online tutoring in that the former allows the student to ask questions on a forum and subsequently have it answered by an expert. The student can even use an online whiteboard to draw a sketch or diagram to accompany the question he or she wants answered. This option is usually less expensive than working with an online tutor and allows the student to ask an unlimited number of questions for a reasonable monthly fee. The expert answers the student’s questions within a short period of time. Another advantage to the student is that all questions and answers are archived and made available for the student to review at a later time. Given this option, a student may find that a question pertaining to a particular topic may have been answered in the past. A homework help site can be ideal for a student of Precalculus in that any question can be asked and then answered by a Precalculus expert.
Conclusion
In conclusion, the Precalculus student must memorize a variety of functions and thoroughly understand their characteristics. The online tutor or even a homework help site can be extremely beneficial in aiding the student to achieve his or her goal of excelling in Precalculus due to their highly interactive and educational nature. The Teaching Tutors will soon be offering a Homework Help Site in addition to its online tutoring services in order to better serve its students!
