Let f: { - pi/3, (2pi)/(3)} rarr [0, 4] be a function defined as f(x)=sqrt(3) sin x - cos x + 2 . Then f^(-1)(x) is given by

Let f:[-(pi)/(3),(2pi)/(3)]rarr[0,4] be a function defined as f(x) as f(x) = sqrt(3)sin x -cos +2 . Then f^(-1)(x) is given by

f:(-(pi)/(2),(pi)/(2))rarr(-oo,oo) defined by f(x)=tan x is

Let f(x)={{:((1-sin^(3)x)/(3cos^(2)x),"if "x lt(pi)/(2)),(a,"if "x=(pi)/(2)),((b(1-sinx))/((pi-2x)^(2)),"if "x gt(pi)/(2)):}" ," if f (x) is continuous at x=(pi)/(2) , find a and b .
