Solution:For f to be continuous f(π/6)=limx→π/6+ f(x)sinπ3=aπ6+b i.e. 32=aπ6+bf′(π/6+)=limh→0+ f(π/6+h)−f(π/6)h=limh→0+ a(π/6+h)+b−sinπ/3h=limh→0+ a(π/6+h)+b−(aπ/6+b)h=a. f′(π/6−)=limh→0− f(π/6+h)−f(π/6)h=limh→0− sin2(π/6+h)−sinπ/3h=2cos2π6=212=1, so a=1,b=32−π6. For these values of a and b, f′(x)=2cos2x0<x≤π/61π/6<x≤1 which is continuous.
