Is Algebra a Practical Science?
Tuesday, June 15th, 2010It is safe to say that algebra is the center of mathematics. If you genuinely want to know about mathematics and its basic principles then you should have a complete and thorough knowledge of algebra. If someone asks you to calculate the product of 223 and 112, you can easily do it manually or with a calculating machine. But when it comes to exponential (e) of 223 and logarithmic (log) of 112 then obviously, you will need some kind of algebraic calculator or algebra problem solver. Graphing a circle will be easy for this given formula X2 + Y2 = 4 but when it comes for an inequality like (X-2)2 + (Y-4)2 > 20 then it will be quite harder to plot the graph. In this situation algebra application can help you a great deal because once you enter the inequality in the program, the graph will get plotted automatically within a fraction of second. These kinds of software packages can easily resolve any kind of algebraic, arithmetical and radical expressions of any kind of complexity.
Domain and Range of a Function
Although, obtaining the domain and range of a function such as Y = X2 can be easily found by considering the number range on the X-Y plane, defining the domain and range of a log(tan 2x + sin 3x) = cosine(-4)(2x) will be way too difficult. But now you can solve such critical and complex problems with an algebra calculator without breaking sweat and you will also be getting all the steps as well
Coordinate Geometry
It is now, easier than ever to find the vertex and directrix or whether a parabola opens up or down, using algebra software. Addition, subtraction and multiplication of polynomials are quite uninteresting, since they involve lots of terms to manipulate. But algebra calculator will do this job in much less time and with 100% accuracy. Solving determinants and matrices of 3×3 or 4×4 order can become very tough since it involves lots of calculation; getting inverse of matrices even more so. However using algebra software packages will make this task much simpler.
So now you need not to start worrying when you see indices, rational numbers or exponential equations. Parabolas, hyperbolas or ellipses can all be easily graphed within computer algebra systems.
