- Hello,
-
- I have just typed your integral into a math-prg and the solution
- of it is just 0.
- The integral is:
- 2 2 2 2 2
- (-1/4 a -3/4c )a ln(x-a) a (1/4a +3/4c ) a ln(x+a)
- (------------------------ - 1/4 ------- + -----------------------
- F E (x-a) F
-
- 2 2 2 2
- a c(3a +c ) ln(x-c) c
- -1/4 ------- + 1/4 ----------------- - 1/4 -------
- E (x+a) F E (x-c)
-
- 2 2 2
- c(3a +c ) ln(x+c) c 4
- -1/4 ----------------- - 1/4 -------) sin x
- F E (x+c)
- with
- 4 2 2 4
- E=a -2a c + c
-
- 6 4 2 4 2 6
- F= -c -3 a c + 3 c a + a
-
- I hope thats right... Christoph
