• Hi, This is Nirma.. I've sent some questions asked in JEST 2010..Will post some more questions soon..

1) X and y are non zero real numbers then the values of x2 + xy + y2 are

Always positive, sometimes positive and negative, always negative, none of these.

2) The value of Lim Re (z2) + Im (z2) / z2
Z tends to 0

Is 1, -1, -i, limit does not exist..

3)A man measures a distance of 50 meters with a stick of 1m length. The man repeats the measurement for 50 times to cover the 50 meters length. In each measurement the values lies between 99.8cm and 100.2 and not beyond this limits. Calculate the error in measurement.

0.82cm, 0.20cm, 10.0cm, 0.40cm.

4) A small moon is rotating around the planet. The astronomer measures the minimum and maximum distance of the moon from the planet and measures the speed of the moon. Using the above data, which of the following is not able to calculate?

hii boom, please look at the denomeantor of 2nd question

2) what is the value of
{integral over closed loop c} (z+1)/(3z^2-2z^2-z) when c is an unit circle about origin.

first and 2nd term have same power of z. did u missed something. please see once again this question and modify it if necessary..

Hi anon @ February 6, 2011 10:42 PM, I think I made a mistake. it should be 2z not 2z^2.

• At February 7, 2011 at 4:25 PM,  Anonymous said…

i think the denominator term is not correct. i think it would be 3z^3-2z^2-z.
