Sketching y=[g(x)]/[f(x)] when already given y= [f(x)]/[g(x)] (2 Viewers)

[blackops23]

Hi guys, as part of a question I had to sketch y=[ln(x)]/x
which I easily completed,
The next part of the question said to sketch y=x/ln(x), without any further calculation, i.e. no calculus.

How do I go about sketching the second function when I already have sketched my first function?

Also in general what should you be doing and what should you be looking if you have to sketch y=g(x)/f(x) when given y=f(x)/g(x)

Thanks guys

Reciprocate it. Easy done bam. Is this really a ext2 maths question?

Take the y coordinates then flip them.

I think you have to take the y coordinates then flip them.

Umm...

I think I have done this question, it appeared in my tutoring work before although I haven't started Year 11 yet, i'm pretty sure you have to take 1/y coordinates

xD why the hell didn't I see that, it's so simple lol...

Only a few more weeks of sleep until the start of Year 11 then I can finally do some REAL maths.
