Question

sqrt( 1 - (x^2) ) ...
find all possible values of x?

Answer 1

\[\sqrt{1 - x^{2}}\]

Answer 2

If you don't include complex numbers x can only be 0, 1 and -1 i think....?

Answer 3

no only real numbers

Answer 4

sqrt is not defind for negative numbers (at least in R)
so 1-x2>0
x2<1
|x|<1

Answer 5

where i put < or > should be <=, >=

Answer 6

we have to find all possible values for x for which the sqrt is possible

Answer 7

|x|<1

Answer 8

-1<x<1

Answer 9

find all possible values for x for which the sqrt is defined

Answer 10

-1<x<1

Answer 11

how did u find it ? can u explain

Answer 12

sqrt is not defind for negative numbers (at least in R)
so 1-x2>0
x2<1
|x|<1

Answer 13

till x2 < 1, i understood but after that i didn't

Answer 14

take sqrt bouth sides, and what you get?
sqrtx2=+-1

Answer 15

ohhhh.. after that plz

Answer 16

sqrtx2 =|x|

Answer 17

ohhhhh.... now i got all .. thanks alot myko :) :)

Answer 18

is someoqne reading my question

Answer 19

it should be \[|x| \le 1\]

Answer 20

eigenschmeigen.. you are right :) :) thanks :) :)
