`n{P[P(phi)]}= ?` where `P(phi)={phi}`
(a).1
(b).2
(c).3
(d).4

If A=phi then write P(A) .

If phi(x)=2^(mx+1) , show that phi(a). phi(b).phi(c)=4.phi(a+b+c).

Verify that |P(phi)|=2^@

Show that n[P[P.(P(phi)))=4

Are phi and {phi} same? n{phi} ?

Show that n(P(P(P( phi))))=4

If P( 3 sec theta, 2 tan theta ) and Q( 3sec phi, 2 tan phi ) " where" theta +phi =(pi )/(2) , be two distinct points on the hyperbola (x^(2))/( 9) -(y^(2))/( 4) =1 . Then the coordinate of the points of intersection of the normals at P and Q is

If (sin^(4)phi)/(a)+(cos^(4)phi)/(b)=(1)/(a+b) then prove that (sin^(8)phi)/(a^(3))+(cos^(8)phi)/(b^(3))=((1)/(a+b))^(3)
