`sinx-cos^2x-1` assumes the least value for the set of values of `x` given by

The least value of sin x.cos x is

The least value of sin x.cos x is

the least value of cos ^2 x + sec ^2 x is

The least value of sin 2x-sqrt(3) cos 2x is

If x^(2)-x+a-3<0 for at least one negative value of x, then complete set of values of 'a is

If "cos"^(-1)x> "sin"^(-1)x , then the set of all values of x is

If 16-x^(2)>|x-a| is to be satisfied by at least one negative value of x, then complete set of values of 'a' is

Let f(x) = cos^(2) x + cos x +3 then greatest value of f(x) + least value of f(x) is equal to

" If "tan^(2)x+sec x=a+1" has at least one solution,then the complete set of values of "a" is "

The least value of cos^(2)x+sec^(2)x is :
