^{NO LINKS PLEASE}Where can I find solutions to R.D.Sharma Maths book ,class XI without registering for it?

find the domain and range of

f(x)=x square/1+x square

Write domain and range of greatest integer function

^{x}/25^{x}+5, show that f(x) + f(1-x)=1^{2}-x+1/x^{2}+x+1 find domain and rangeexplain too

thanks !

find domain and range:

f(x) = 1/2-sin 3x

also find f(-2) and the numbers which are associated with the numbers -25 in its range.

dear experts please explain me what the second part of the question means with the answer

write all the possible relations from A={1,2} to B={0}

f(x)=|x-4|/x-4

i) [-3, 0]

ii)[1, 2]

iii)[2, 3]

iv)[3, 4]

find the domain and range of 3/2-x^2

find domain and range

f(X)=1/{sqrt(5)-x}

how can you find the range and domain of root of

^{}(9-x^{2})?If

y=(x+1)/(2x+1)=f(x)&x=g(y), then find.g(y)i) (-infinity,0]

ii) [0,infinity)

iii) R

iv) R - {x:g(x)=0, x belongs to R}

f(x)=3/(2-x^2) find the range and domain of the function

^{2}-16/ x+4^{2})Shouldn't it be like , if A and B have one element in common then , n {(AxB) intersection (BXA)} also be one and if A and B have 2 elements in common then , n {(AxB) intersection (BXA)} be 2 and like wise for 3 ,4,5 ... But it's given that if A and B have 3 elements in common then , n {(AxB) intersection (BXA)}=9 How is this possible , we don't repeat same elements in the intersection of sets . Please someone explain clearly .

by using properties prove that

(i) a U b = a intersection b imlies a=b

(ii) for any sets a and b show that p(a intersection b) = p(a) itersection p (b)

(iii) if a,b And c be the sets such that aUb = aUc and a intersection b = a itersection c show that b = c

(iv) a intersection (aUb) = a and aU(a intersection b) = a

n(A)=p and N(B) = q.
