Screamin' seafaring tale wins bad writing contest The Associated Press all 299 news articles » From Google News Search: "imaginary" What happens when a number is raised to an imaginary power? Q. What happens when a number is raised to an imaginary power, say i? Can you show how your answer can be derived from the definition of i as (-1)^1/2 (assuming it can be without supplemental stipulation). Finally, a response without reliance on trigometric notation would be appreciated. Thanks in advance. Asked by Anthony D - Fri Dec 26 20:47:32 2008 - - 8 Answers - 0 Comments A. Actually multiplying imaginary numbers and using them in exponents is not so weird or unnatural at all. Imaginary numbers are an essential part of our understanding of reality in the universe. Here is a way to think about them without trigonometry, assuming you are familiar with power series expansions. If you're not, learning about them, at the right time, is a good step in everyone's intellectual development. First, the function e^x is equal to the following infinite sum: e^x = 1 + x + x^2/2 + x^3/3*2 + x^4/4*3*2 + x^5/5*4*3*2 + ... So put in i for x and you get e^x = 1 + i + i^2/2 + i^3/3*2 + i^4/4*3*2 + i^5/5*4*3*2 + ... Because i^2=-1, i^3=-i, i^4=1, i^5=i, etc, this is the same as e^x = 1 + i - 1/2 - i/3*2 + 1/4*3*2 +… [cont.] Answered by Leslie W - Fri Dec 26 22:44:13 2008 How do I solve the following Polynomial for positive, negative and imaginary zeroes? Q. How do I solve 9x^3-7x^2+10x-4 for positive, negative and imaginary real zeroes? I have tried and come up with a number close to 4/9 but it is not a solution.

Just as there is a procedure for quadratics, there is also a procedure for cubics: but if you haven't studied this, it isn't likely that that's what is expected. If you are looking for a numerical solution (as opposed to a symbolic one), you can note that: F(1) > 0 and F(0) < 0 so there must be at least one positive root (i.e. between 0 and 1) so you can use a number of numerical methods to find it. (Bisection, Newton's method, secant method, etc.) Once you have the root r, you can divide F(x) = 9x^3-7x^2+10x-4 by (x - r) to get a quadratic. Then you can apply the formula that I'm sure you have been taught to get the roots of the quadratic.

Q. I'm learning about imaginary numbers in Algebra II right now, and I'm thinking, what's the point? If the numbers are imaginary and don't really exist, then why must we learn about them? When would we ever have to use these kinds of numbers in life, like in a job or career of some sort, if they're imaginary and don't exist? Also, if you know how and why these numbers are used in those careers, then please do tell. Thanks. Asked by Ari Bo Bari - Fri Oct 19 13:28:19 2007 - - 11 Answers - 1 Comments A. Don't let the name fool you. Imaginary numbers do have real life uses. Together, the use of imaginary numbers with the real numbers to make numbers of the form a+bi form the complex numbers, to which the real numbers a+0i is simply a subset of. In fact, the natural numbers, rational numbers, integers, and real numbers are as much of an invention as the complex numbers are. We first started using natural numbers to quantify discrete quantities such as how many apples are in the basket. This number system serves its purpose here well, but it has its limitations. For instance, what if you want to discriminate between having 4 apples and owing 4 apples? Or gaining 4 more apples versus losing 4 more apples? This is when we invented the… [cont.] Answered by J Bareil - Fri Oct 19 14:10:09 2007 From Yahoo Answer Search: "imaginary" |
