1i think answer is B.
If f(x)+f(x+a)+f(x+2a)...f(x+na)=0,where a>o,, then the period of f(x) is what?
a> a
b> (n+1)a
c> a/(n+1)
d> Non-periodic
Please show me the method, sir.
ps.:by the way, nishanta sir, i found your techniques to find period quite useful.thanks to your technique i could find easily the period of f(x)=2 raised to the power (sin3(3.14x)+{x}), where {} is a fractional part function. Thank you

1357put x=x-a and subtract from first
you will get f(x-a)=f(x+na)
now put x=x+a
this might solve your problem
1oh yes sir..thanks for the method..thank you ronald also for your tym and effort..
