(1) Decide whether the following limits exist or not. Evaluate the values if
they exist.
(a) (20pt)
lim sin(x+π/3)-1
x→π/6 --------------
x-π/6
(b) (20pt)
f(x)=x^2-4x
lim f(x)-f(2)
x→4 ---------
x-3
(c) (20pt)
lim f(x)
x→4
x^2 , x<4
where f(x)= 15 , x=4
3x+4 , x>4
(2) For what values of A is the following f continuous at x=2? (20pt)
f(x)= A^2x^2 , x≦2
(1-A)x , x>2
(3) Set f(x)= x^2-x , x≦2
2x-2 , x>2
