If `x^2-2x+sin^2theta=0` then x belongs to

If sin^(-1)(2xsqrt(1-x^(2)))-2 sin^(-1) x=0 then x belongs to the interval

If sin^(-1)(2xsqrt(1-x^(2)))-2 sin^(-1) x=0 then x belongs to the interval

"I : If tanh"^2 x = sin^2 theta" then sech x = cos "theta "II : coth x = sec " theta" cosech x = sin " "theta"

x^(2)-2x+2cos^(2)theta +sin^(2)theta=0 , then maximum number of ordered pair (x, theta) such that x ∈ R, theta ∈ [0,2pi] .

x^(2)-2x+2cos^(2)theta +sin^(2)theta=0 , then maximum number of ordered pair (x, theta) such that x ∈ R, theta ∈ [0,2pi] .

If roots of the equation 2x^(2)-4x+2sin theta-1=0 are of opposite sign then theta belongs to

If 2x= sin theta and 2/x=cos theta , then the value of 4(x^2+1/x^2) is: यदि 2x= sin theta और 2/x=cos theta , तो 4(x^2+1/x^2) का मान है:
