Homework Statement
Let a,b and c be lengths of sides in a triangle, show that
√(a+b-c)+√(a-b+c)+√(-a+b+c)≤√a+√b+√c
The Attempt at a Solution
With Ravi-transformation the expressions can be written as
√(2x)+√(2y)+√(2z)≤√(x+y)+√(y+z)+√(x+z).
Im stuck with this inequality. Can´t find a way to...
1.
Find the Fourier series of :
$$g(t)=\frac{t+4}{(t^2+8t+25)^2}$$
2. I have been trying to write the function to match the formula $$\mathcal{F} [\frac{1}{1+t^2}] = \pi e^{-\mid(\omega)\mid}$$
3.
I have simplified the function to
$$(t+4)(\frac{1}{9}(\frac{1}{1+\frac{(t+4)^2}{9}})^2)$$...
