Usually in hot desert, because of the hotness of the sand the density of the air which is close to it decreases and as we go higher/upper the density of air relatively increases so we can imagine them as layers.(as the pic has shown)
As we know that light changes its direction and speed...
Homework Statement
Find the domain and range:
{ x+2, x\leq0
f(x) ={x3, |x|<1
{-x+3, x\geq1
Homework Equations
domain = possible inputs
range = possible outputs

In binary can we have a value with "deci" "centi" "mili" or more lower valued prefix?
i have learned that,
1 Kilo Byte = 210 byte
1 Miga byte = 220 byte
. . . .
1 Yotta byte = 224 byte
Now my question is, can we have a DECI, CENTI, MILI bytes? i assume the answer could be negative...
Sin (a + a) = sin a cos a+ cos a sin a
=> Sin 2a = 2Sin a Cos a
=> SIN B = 2 Sin (B/2) Cos (B/2) [2a = B] . . . . (i)
Cos (a + a) = cos a cos a - sin a sin b
=> cos 2a = cos^2 (a) - sin^2 (a)
=> cos 2a = (1 - sin^2 (a) ) - sin^2 a
=> cos 2a = 1 - 2sin^2 (a)
=> 1 - cos 2a = 2s n^2 (a)...
infity means INFINITY, dude! Just plusing or minusing some lil value rather than another infinity doesn't really bother to hamper its value at all...
For example when you fill a bottle with sea water, the water level does not really change that negligible, right? And infinity is much more huge...
