If 0

The general solution of 2 sin^(2)theta - sin theta - 1 = 0 is

If alpha,beta are roots of z^(2)sin^(2)theta-z sin2 theta+1=0 where '0

If 6sin^(2)theta - sin theta = 1 and 0 le theta le pi , what is the value of sin theta ?

The number of roots of the equation 2 sin^(2)theta + 3 sin theta + 1 = 0 in (0, 2pi) is

Number of values of theta which satisfy sin^2theta-2sin^2theta-1=0 is

If sin^(2)theta - 2 sin theta - 1 = 0 is to be satisfied for exactly 4 distrinct value of theta in[0,npi],n in N , then the least value of n is :

If cos theta+cos^(2)theta=1 then sin^(2)theta+2sin^(2)theta+sin^(2)theta=

If theta in(0,2 pi) and 2sin^(2)theta-5sin theta+2>0 then the range of theta is

If "sin"^(2) theta -2"sin" theta-1 = 0 is to be satisfied for exactly 4 distinct values of theta in [0, n pi], n in Z , then the least values of n, is
