1.Let f(x) = (1+x)^ (1/2) + (1-x)^ (1/2)
(a) Find the Maclaurin series for f
(b) Find (4) (51)
f (0) and f (0)
请问(a)是要我导马克的公式吗? (b)小题 我不会算
2.
(a) Evaluate ∫∫ e^(x+y) where R is given by the inequality
R
｜x｜+｜y｜≦1.
(b) Let f be continuous on [0,1] and R be the triangular region with
vertices (0,0),(1,0)and (0,1) show that
∫∫f(x+y)dA = ∫[0,1] uf(u)du
R
谢谢~~
