Homework Statement


Let f_1(x) and f_2(x) be odd and even functions respectively. How can we construct an even function out of these?


Homework Equations


f_1(x)=-f_1(-x)
f_2(x)=f_2(-x)


The Attempt at a Solution

Are there any restrictions to what we can do?

f_1(x)f_2(x) would be an odd function, can you show why?

Then we could supposedly square the entire thing and end up with an even function... But I don't know exactly what you're looking for.
 


No, there are no restrictions to what we can do.
yes, I can see that it is an odd function since it gives me-
<br /> -f_1(-x)f_2(-x)<br />

Right, so is squaring the product of the functions enough here, or are you looking for something more?
 
There are two things I don't understand about this problem. First, when finding the nth root of a number, there should in theory be n solutions. However, the formula produces n+1 roots. Here is how. The first root is simply ##\left(r\right)^{\left(\frac{1}{n}\right)}##. Then you multiply this first root by n additional expressions given by the formula, as you go through k=0,1,...n-1. So you end up with n+1 roots, which cannot be correct. Let me illustrate what I mean. For this...
