Integration

數學小子

好難,完全冇頭緒
Slove the following integration:
a) in [x^1/2/(1+x^3/4)]dx
b) in sqrt[(1-x)(1+x)]/x dx
c) in (2+x)/sqrt(4x²-4x+5)dx
d) in dx/[x+sqrt(x²-x+1)]
e) in dx/(2sinx+sin2x)
f) in e^3x(cot²x-3cotx+1)dx

-終場ソ使者-

a) Let ,




b) Let

(...既只係簡單運算,我唔打埋出黎啦)

c)



d)試下自己做啦
e) (Let t=cosx)

f)諗緊,呢條真係幾難-.-
