If A={p,q,r} and B={q,p,r}. Then check whether A=B or not.

If A = {p,q,r, s} and B = {1, 2, 3} , find which of the following is not a function from A to B?

Consider the sets A ={p,q,r,s} and B={1,2,3,4}. Are they equal?

If P={a,b,c} and Q={r}, form the sets P xx Q and Q xx P . Check if the products are equal or not?

If n(A) = p and n (B) = q then numbers of non void relations from A to B are (2^(p+q)-1) .

If tan(A+B)=p and tan(A-B)=q , then show that tan2A=(p+q)/(1-pq) .

If p,q and r are in AP the value of determinant |{:(a^(2)+2^(n+1)+2p,b^(2)+2^(n+2)+2q,c^(2)+p),(2^(n)+p,2^(n+1)+q,2q),(a^(2)+2^(n)+p,b^(2)+2^(n+1)+q,c^(2)-r):}| is

lf r, s, t are prime numbers and p, q are the positive integers such that their LCM of p,q is r^2 t^4 s^2, then the numbers of ordered pair of (p, q) is

Let S=sum_(r=1)^(117)(1)/(2[sqrtr]+1) , when [*] denites the greatest integer function and if S=(p)/(q) , when p and q are co-primes, the value of p+q is

If p,q,r are in G.P. and the equations, px^(2) + 2qx + r = 0 and dx^2+2ex + f = 0 have a common root, then show that d/p , e/q, f/r are in A.P.

If pnea,qneb,rnec and |{:(p,b,c),(a,q,c),(a,b,r):}|=0 then prove that p/(p-a)+q/(q-b)+r/(r-c)=2
