सिद्ध कीजिए कि `f(x) = x^(2)` द्वारा परिभषित `f: IR to IR` आच्छादक नहीं है ।

If f(x) =(x^2) , then f@ f(x) =

सिद्ध कीजिए कि |vecA xx vecB|^(2) + |vecA * vecB|^(2) = (AB)^(2).

If f(x) = x -[x] then f(x) at x= 2 f(x) is

If f(x)= (x^2+px+4) and (x-3) is a factor of f(x) the what is the value of p? यदि f(x)= (x^2+px+4) तथा (x-3) ,f(x) का गुणनखण्ड है, तो p का मान क्या है?

Let f : R rarr R be defined by f(x) = 3x - 2 ad g : R rarr R be defined by g(x) = (x+2)/(3) . Shwo that fog = I_R = gof

{x in IR : cos 2x + 2 cos^(2) x - 2 = 0}=

Ir x in (0 ,(pi)/(2) ) " then " int sqrt(1 + cos x ) dx =
