試題 :
I.
A). Let f(x) = { x^2 , x＜1 Find A given that f is continuous at 1.
{Ax-3 , x≧1.
B). Give necessary and sufficient condition on A and B for the function
{ Ax-B , x≦1
f(x) ={ 3x , 1＜x＜2
{Bx^2-A , 2≦x
to be continuous at x=1 but dis continuous at x=2.
II.
A). Show that, for all real numbers c,
1-cos x
lim Sin x = Sin c , lim ──── = Cos c
x→c x→c x
B). Prove that
Sin x 1-cos x
lim ──── = 1 and lim ──── = 0
x→0 x x→0 x
III.
A). Find f'(x) given that f(x) ={ x^2, x≦1
{2x-1, x＞1 .
B). Show that if f is diifferentiable at x, then f is continuous at x.
