(-oo;-oo)sin[(1)/(2)cos^(-1)(4)/(5)]

f(x)=(x-2)|x-3| is monotonically increasing in (a)(-oo,(5)/(2))uu(3,oo)(b)((5)/(2),oo)(c)(2,oo)(d)(-oo,3)

int_(-oo)^(oo)(1)/(1+x^2) dx

The inequality (2)/(x)<3 is true,when X belongs to (A)[(2)/(3),oo](B)[-oo,(2)/(3)](c)((2)/(3).oo)uu(oo,0)(D) none of these

Consider the function f(-oo,oo)rarr(-oo,oo) defined by f(x)=(x^(2)-a)/(x^(2)+a), agt0 which of the following is not true?

Evaluate int _(-oo) ^(oo) (1)/(1 + x ^(2)) dx.

The domain of the function f(x)=1/(sqrt(|x|-x)) is: (A) (-oo,oo) (B) (0,oo (C) (-oo,""0) (D) (-oo,oo)"-"{0}

The function f(x)=cot^(-1)x+x increases in the interval (a)(1,oo)(b)(-1,oo)(c)(-oo,oo)(d)(0,oo)

The domain of the function f(x)=1/(sqrt(|x|-x)) is: (1) (-oo,oo) (2) (0,oo (3) (-oo,""0) (4) (-oo,oo)"-"{0}

The domain of the function f(x)=1/(sqrt(|x|-x)) is: (1) (-oo,oo) (2) (0,oo (3) (-oo,""0) (4) (-oo,oo)"-"{0}
