If x takes negative permissible vlaue then `sin^(-1)x=`

All the permissible value of b ,a=sin(2x-b)if a=0 and x=S_(2) is a subset of (0, pi) are given by

A random variable X can take all non-negative integral values and the probabililty that X takes the value r is proportional to alpha^(r)(0

Consider a quadratic expression f (x) =tx^(2) -(2t -1) x+ (5x -1) If f (x) can take both positive and negative values then t must lie in the interval

If the inequality sin^(2)x+a cos x+a^(2)>1+cos x holds for any x in R, then the largest negative integral value of a is -4(b)-3(c)-2(d)-1

If the minimum value of the quadratic expression y =ax ^(2)+bx +c is negative attained at negative vlaue of x, then :

If sqrt((1-sin A)/(1+sin A))+(sin A)/(cos A)=(1)/(cos A) for all permissible values of,then A can belong to

If the inequality sin^(2)x+a cos x+a^(2)>1+cos x holds for any x in R, then the largest negative integral value of a is -4( b) -3(c)-2 (d) -1

Consider the function defined by f(x)=(sin x)/(sqrt(1+tan^(2)x))+(cos x)/(sqrt(1+cot^(2)x) for permissible value. Then f(x)=0 (n is an integer) for
