ses x - cos x = K1
cosec x- sin x = k2
the eliminant of x between the equation is
a) ( K22*K1)2/3 + (K2*K12)2/3 =1
b) K22 + K12K22 = 2
c) K12/3*K22/3(k12/3 + K22/3) = 1
d) K1*K22 + k2*K12 = 2

62soumi this could be much easier than you think
just use the fact that k1=sin^2x / cos x
and k2=cos^2 x / sin x
1secx - cosx=k1 or 1 - cos2x=k1cosx or k1=sin2x/cosx similarly for k2=cos2x/sinx now put the values of k1 and k2 in the options given and see which options are correct....
