ok.. thank.. maybe i should read up cachy principal again..

From observation, we already know that the function is an odd function, but What i mean is solve and proof it that the equation is an odd function. what i mean is solve and proof it mathematically if possible.

tat true.. if the limit is from A to -A or even from Infinity to -Infinity, the result will be zero. If it is undefined, say like limit from A to B den the answer should not be zero. right ? This question in the first place was just to solve it to be odd function using mathematical approach...

Okie.. Thank every1 for the guide and comment given.

Oh.. I only know the shortcut method but don't know whether u are referring to it or not... I only know that 't' is odd function and cos(10t) is even function.. so multiply odd with even will give me odd function... I'm confused is the part on how to solve it mathematically said...

Hi, having difficulty solving the following question.. Any1 can help me and guide me through solving it ?? or is there any good website or reference to recommand ?? Thankz alot..
