sin (1/x)
What I tried to do is to find the max and min but i'm having some trouble with that.. because as an answer i got 1/90 degrees for one of em..
Thanks
Its actually my assignment sigh...
and during our exams we're not allowed calculators but usually I guess not *that* extreme but yeah... i just don't get how you figure it out by like normal math..
I even tried taking the derivative to find max but after finding it i tried putting y as 1 but it didn't really work out because i couldn't solve it...
One thing you could do is treat it as a series.
$\displaystyle f(n)=sin(\frac{1}{n\pi})=0 $
So the domain is the natural numbers. Then just plot the points on the x-axis. The amplitude should still be 1.
Label the x-axis as a series too: $\displaystyle \frac{1}{n\pi}$
It's still difficult, but this will make it a little easier. I don't see any easy way to just sketch this using conventional methods.
