" 07.If "A={0(k)/(6),(pi)/(4)*(pi)/(3),(pi)/(2)}" and "f:A rarr B,f(x)=cos x" is surjection find "B

If A={0 , pi/6, pi/4, pi/3, pi/2} and f: A rarr B is a surjection defined by fx) = cosx then find B

Function f[(1)/(2)pi, (3)/(2)pi] rarr [-1, 1], f(x) = cos x is

f(x)=cos2x, interval [-(pi)/(4),(pi)/(4)]

Let f(x)=(1-tan x)/(4x-pi),x!=(pi)/(4),x in[0,(pi)/(2)], If f(x) is continuous in [0,(pi)/(4)], then find the value of f((pi)/(4))

The function f(x)={x+a sqrt(2)sin x,0<=x<=(pi)/(4) and 2x cot x+b,(pi)/(4)<=x<=(pi)/(2) and a cos2x-b sin x,(pi)/(2), is continuous for 0<=x<=pi ,then value of a,b are

Let f(x)={:{((kcosx)/(pi-2x)',xne(pi)/(2)),(3",",x=(pi)/(2).):} If lim_(xrarr(pi)/(2))f(x)=f((pi)/(2)), find the value of k.

f(x)={x+sqrt(2)a sin x,0

If f(x)=0 is a quadratic equation such that f(-pi)=f(pi)=0 and f((pi)/(2))=-(3 pi^(2))/(4) then lim_(x rarr-pi)(f(x))/(sin(sin x)) is equal to (a)0( b) pi (c) 2 pi (d) none of these

If f(x)=0 be a quadratic equation such that f(-pi)=f(pi)=0 and f((pi)/(2))=(-3 pi^(2))/(4), then lim_(x rarr pi)(f(x))/(sin(sin x)) is equal to:

If f(x)=0 be a quadratic equation such that f(-pi)=f(pi)=0 and f((pi)/(2))=(-3 pi^(2))/(4), then lim_(x rarr pi)(f(x))/(sin(sin x)) is equal to:
