i m just trying.... if z>=3 what can u say about 1/z ??

I Did nt Understand....wat is here Least..""

hartnnBest ResponseYou've already chosen the best response.1
means z+1/z is > = 'some number' u need to find that number.

but z+1/z <= z+1/z how did u get > sign there ?

u see..i have inserted a ve there....Since it asks for least value."

Hmm.. Am I right for this: z ≥ 3 i.e. z ≥ 3 or z ≤ 3 ?

i think z is complex here, isn't it @Yahoo! ??

hartnnBest ResponseYou've already chosen the best response.1
so z>= 3 represents region outside the circle with radius 3.....if i have not misinterpreted

\[z \geq 3\implies z\leq3\;or\;z\geq3\] \(\leftz + \frac1z\right\) is just a symmetrical hyperbola about Yaxis. If you're well versed with hyperbola you will get the idea of the graph with constraint \(z\geq3\).

lol...i Dont knw Hyperbola....

Okay. \[x + \frac1x\] \(x\) is ever increasing, so to find the minima of \(x + \frac1x\) you should find value for which \(x\) is minimum i.e 3 as \(1/x\) is decreasing for \(x>1\).

Ishaan94Best ResponseYou've already chosen the best response.0
Important to note \(1/x\) is decreasing not negative.
 one year ago

Ishaan94Best ResponseYou've already chosen the best response.0
Negative with respect to \(x\).

express Z= x+ iy.......and its mod value is suar root of x^2 +y^2.....now mod of Z+1 can be expressed as (x+1 )+ iy......and then solve it.....i know its very lengthy but it works when u have no other option....

If r is the modulus of z, then z+ 1/z >= r  1/r. Now the minimum of r  1/r for r>=3 is clearly 3  1/3 = 8/3. The minimum for z+1/z is attained if z = 3 and if z and 1/z have opposite directions. Take z = 3i so that z = 1/3i =  i / 3, and the minimum 8/3 is attained for that value. Can u Explain this!

shouldn't it be this way? or is something wrong with this? dw:1347108277591:dw

if its <= then its max value , not least value.

The answer should be 8/3

hartnnBest ResponseYou've already chosen the best response.1
and yes,thats the correct way to find max value.

lol.....Can we Do like this z ( 1/z) > = z  1/z
