试题 :
1. (20%) Find lim x->0 (x/(sinx)^2) - sinx/x^2
2. (20%) Evaluate lim n->∞(1/n)[ln((n+1)/n)/((n+1)/n)
+ ln((n+2)/n)/((n+2)/n)
+ .....
+ ln((n+n)/n)/((n+n)/n)]
3. (15%) Show that, for x > 0, 1/(1+x^2) < tan^-1(x) < x.
4. (10%) Evaluate ∫0 to 4 |x^(1/2) - 1|dx
5. (15%) Is it possible that the equation 3x = 2cosx + 5 has more than one
real root? Give reason to justify your answer. (You can draw the graphs
y = 3x and y = 2cosx + 5 to justify your claim.)
6. (0%) Find y' and y'' of the curve x^y = y^x
注: 超出范围，本题不算分

(a) Domain, (b) Intercepts, (c) Symmetry,
(d) Asymptotoes, (e) Intervals of Increase and Decrease
(f) Local Maximum and Local Minimun,
(g) Concavity and points of Inflection, (h) Sketch of the Curve
