bhai sab ko square karke add karde...

@snkr87 said: puys pls solve n giv explan..
X= r sinA cosC ,Y=r sinA sinC ,Z=r cosA find the value of X^2+Y^2+Z^2=...?
opt (1-r^2)/r^2/1+r^2/1
Answer = r^2 ???
1317
@JS-M said: if x, y, z are real numbers such that x + y + z = 5 and xy + yz + zx = 3, what is the largest value x can take(a)5/3 (b)13/3 (c)19 (d) none of these
explain neone???

A man rides at 350 mtr/min & stops 6min to change horse at the end of every sixth km.. Then to travel a distance of 84 km the time taken by the man is...?

@visitsameer said: When the Subjects joined by 'or/nor are of different numbers, the Verb must be Plural, and the Plural Subject must be placed next to the Verb.
bhai what do u mean???
1323
@truly.gone said:
bhai simply put value x 13/3 and y,z 1/3 ....dusre kisi values se equation match nehi ho raha
bhai none of these bhi toh ho sakta hain then????

@visitsameer said:
answer is d......square root of 19.....
explain???
1326
@visitsameer said:
(x+y+z)^2 = x^2 +y^2+Z^2 +2(xy+yz+zx)
25=x^2 +y^2+Z^2 + 2*3
19=x^2 +y^2+Z^2
for max of x , y=z=0
so x =rt19
bhai if answer is rt19 with y=z=0 then it does not satisfy the above 2 equations???
