1ya it is better to learn a formula, than to learn its derivation
11y=0∫∩/2sinmx.cosnxdx
y=0∫∩/2sinmx.(1-sin2x)n-2dx
take sinx=t
y=0∫1tm.(1-t2)n-3dt
solve by parts ull get walis...
i hope

1@ voldemort .. shut up and don't open this thread agen no one told u to post ur stupid messages here ..
@ Scientist .. look at the chapter of integration u will understand the question.
1can ny1 tell what this formula is so that v jouniours can also benfit out of it, if not the derivation, then only the formula....nything is better than nothing...:)
1u dont waste ur and others time by posting such questions and rubbish in the chat box
1yaar i am not against rote memory .. but in Walli's theorem their are 4 cases .. if u forget what one to apply ... what will u do ... my riddle can be solved in 4 steps ...
1so according to riddle no need to learn a formula, derive it, during the exam first derive the formula and then use it.[5]
according to post 6 by riddle, we shud not learn the formula, we must learn its derivation [9]
1that's why i posted my riddle .. if u know the derivation no need to store in memory dude ....
