A
log|sec 2x| – 
log|sec 3x| – 
log|sec 5x|+C
B
log|sec 2x|+ 
log|sec 3x|+ 
log|sec 5x|+C
C
log|sec5x|– 
log|sec 2x|– 
log|sec 3x|+C
D
None of the above
Text Solution
Verified by ExpertsThe correct answer is:
C
tan 5x = tan (3x + 2x) = 
⇒ tan 5x – tan2x. tan 3x. tan 5x = tan 2x + tan 3x
⇒ ∫ tan2x. tan3x. tan5x dx = ∫ tan5x – tan2x – tan3x. dx
Now solve.........
